То се съпътства от редица ефекти, които могат да бъдат вредни или полезни, например: </p> <ul><li><i>Топлинно действие на тока</i> – когато дадена електрическа верига е затворена, по нея протича ток и проводниците се нагряват, това говори за превръщането на електричната в топлинна енергия. Това е известно като <a href="/wiki/%D0%95%D1%84%D0%B5%D0%BA%D1%82_%D0%BD%D0%B0_%D0%94%D0%B6%D0%B0%D1%83%D0%BB_%E2%80%93_%D0%9B%D0%B5%D0%BD%D1%86" title="Ефект на Джаул – Ленц">ефект на Джаул – Ленц</a>. Топлинното действие на електрическия ток се използва в домакински уреди като <a href="/wiki/%D0%A4%D1%83%D1%80%D0%BD%D0%B0" title="Фурна">фурната</a>, <a href="/wiki/%D0%9A%D0%BE%D1%82%D0%BB%D0%BE%D0%BD" class="mw-redirect" title="Котлон">котлона</a> или <a href="/wiki/%D0%91%D0%BE%D0%B9%D0%BB%D0%B5%D1%80" title="Бойлер">бойлера</a>. Всички електроуреди имат нагреватели (проводници от специален метал със сравнително голяма площ), които отделят тази топлина, а съединителните проводници почти не се нагряват.</li> <li><i>Светлинно действие на тока</i> – то се използва в електрическите крушки и други осветителни тела. Електрическият ток нагрява жичката на лампата до температура, при която тя започва да излъчва във видимия диапазон. Само малка част от енергията се превръща в светлина, останалата се превръща в топлина. Други светлинни източници, които превръщат ефективно електрическата в светлинна енергия, са <a href="/wiki/%D0%A1%D0%B2%D0%B5%D1%82%D0%BE%D0%B4%D0%B8%D0%BE%D0%B4" title="Светодиод">светодиодите</a>.</li> <li><i>Механично действие на тока</i> – използва се в електромоторите, когато през електромотора протича ток, той превръща електричната енергия в енергия на движението. Енергията на движение е вид <a href="/wiki/%D0%9C%D0%B5%D1%85%D0%B0%D0%BD%D0%B8%D1%87%D0%BD%D0%B0_%D0%B5%D0%BD%D0%B5%D1%80%D0%B3%D0%B8%D1%8F" title="Механична енергия">механична енергия</a>. Друг вид механична енергия е енергията на <a href="/wiki/%D0%97%D0%B2%D1%83%D0%BA" title="Звук">звука</a>. Някои устройства, които преобразуват електричната енергия в звук, са <a href="/wiki/%D0%92%D0%B8%D1%81%D0%BE%D0%BA%D0%BE%D0%B3%D0%BE%D0%B2%D0%BE%D1%80%D0%B8%D1%82%D0%B5%D0%BB" title="Високоговорител">високоговорители</a>, алармени системи, електрически звънец и други.</li> <li><i>Магнитно действие на тока</i> – най-общо казано, протичането на електрически ток винаги създава <a href="/wiki/%D0%9C%D0%B0%D0%B3%D0%BD%D0%B8%D1%82%D0%BD%D0%BE_%D0%BF%D0%BE%D0%BB%D0%B5" title="Магнитно поле">магнитно поле</a>. Силовата структура на магнитното поле се описва чрез затворените силови линии (концентрични окръжности в случай на праволинеен проводник). Магнитното действие е тясно свързано и с механичното.</li> <li><i>Химично действие на тока</i> – електролизата е пример за това действие. Приложението е във всички видове акумулатори.</li> <li><i>Физиологично действие на тока</i> – това е действието върху живи същества, което е твърде сложно и многообразно. Токът засяга белите дробове, <a href="/wiki/%D0%A1%D1%8A%D1%80%D1%86%D0%B5" title="Сърце">сърцето</a> и нервната система. Може да доведе до спиране на сърцето и <a href="/wiki/%D0%A1%D0%BC%D1%8A%D1%80%D1%82" title="Смърт">смърт</a>. Пораженията зависят от големината на тока, от продължителността на действието и от това през коя част на тялото преминава. Големината на тока от порядъка на 10 – 20 mA се счита за опасна за здравето и живота на човек.</li></ul> <div class="mw-heading mw-heading2"><h2 id="Вижте_също"><span id=".D0.92.D0.B8.D0.B6.D1.82.D0.B5_.D1.81.D1.8A.D1.89.D0.BE"></span>Вижте също</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%82%D0%BE%D0%BA&veaction=edit&section=9" title="Редактиране на раздел: Вижте също" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%82%D0%BE%D0%BA&action=edit&section=9" title="Edit section's source code: Вижте също"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/%D0%A2%D0%BE%D0%BA%D0%BE%D0%B2_%D1%83%D0%B4%D0%B0%D1%80" class="mw-redirect" title="Токов удар">Токов удар</a></li> <li><a href="/wiki/%D0%A2%D0%BE%D0%BA%D0%BE%D0%B2_%D1%82%D1%80%D0%B0%D0%BD%D1%81%D1%84%D0%BE%D1%80%D0%BC%D0%B0%D1%82%D0%BE%D1%80" title="Токов трансформатор">Токов трансформатор</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Източници"><span id=".D0.98.D0.B7.D1.82.D0.BE.D1.87.D0.BD.D0.B8.D1.86.D0.B8"></span>Източници</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%82%D0%BE%D0%BA&veaction=edit&section=10" title="Редактиране на раздел: Източници" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%82%D0%BE%D0%BA&action=edit&section=10" title="Edit section's source code: Източници"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><span class="citation reference"> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20120127174351/http://phys.tu-sofia.bg/ef/Phys%201/Lektzii/Elektrichestvo/28%20vupros.pdf">Електрически ток – големина, плътност и посока</a>, архив на <a rel="nofollow" class="external text" href="http://phys.tu-sofia.bg/ef/Phys%201/Lektzii/Elektrichestvo/28%20vupros.pdf">оригинала</a> от 27 януари 2012<span class="printonly">, <a rel="nofollow" class="external free" href="https://web.archive.org/web/20120127174351/http://phys.tu-sofia.bg/ef/Phys%201/Lektzii/Elektrichestvo/28%20vupros.pdf">https://web.archive.org/web/20120127174351/http://phys.tu-sofia.bg/ef/Phys%201/Lektzii/Elektrichestvo/28%20vupros.pdf</a></span><span class="reference-accessdate">, посетен на 28 ноември 2010</span></span><span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&rft.genre=book&rft.btitle=%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8+%D1%82%D0%BE%D0%BA%C2%A0%E2%80%93+%D0%B3%D0%BE%D0%BB%D0%B5%D0%BC%D0%B8%D0%BD%D0%B0%2C+%D0%BF%D0%BB%D1%8A%D1%82%D0%BD%D0%BE%D1%81%D1%82+%D0%B8+%D0%BF%D0%BE%D1%81%D0%BE%D0%BA%D0%B0&rft_id=https%3A%2F%2Fweb.archive.org%2Fweb%2F20120127174351%2Fhttp%3A%2F%2Fphys.tu-sofia.bg%2Fef%2FPhys%25201%2FLektzii%2FElektrichestvo%2F28%2520vupros.pdf&rfr_id=info:sid/en.wikipedia.org:%D0%95%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%82%D0%BE%D0%BA"><span style="display: none;"> </span></span></span> </li> <li id="cite_note-2"><span class="mw-cite-backlink"><a href="#cite_ref-2">↑</a></span> <span class="reference-text"><a rel="nofollow" class="external text" href="http://physics-bg.org/au/043-eltok.php">Постоянен електричен ток, посока и големина на тока</a> physics-bg.org, Ваньо Георгиев</span> </li> <li id="cite_note-3"><span class="mw-cite-backlink"><a href="#cite_ref-3">↑</a></span> <span class="reference-text"><cite class="book" style="font-style:normal"><a rel="nofollow" class="external text" href="https://web.archive.org/web/20220327183648/https://quizlet.com/269683782/%D0%A4%D0%B8%D0%B7%D0%B8%D0%BA%D0%B0-flash-cards/">quizlet.com</a> //    Архивиран от <a rel="nofollow" class="external text" href="https://quizlet.com/269683782/%D0%A4%D0%B8%D0%B7%D0%B8%D0%BA%D0%B0-flash-cards/">оригинала</a> на 2022-03-27.
