However, this property is also important in a direct current circuit as seen\u00a0here. An open circuit has no current, but the moment the switch is closed, current will begin to flow. The inductor, resisting the sudden change in voltage, will resist current flow at first. The lamp, since it is parallel to the resisting inductor, will light up immediately without difficulty. However, the inductor will soon \u201cget used\u201d to the current flow, and the resistance of its path will drop significantly. As more current flows through the easy inductor path, the total current (and therefore energy use) of the circuit will increase significantly as the overall resistance drops. (D) is exactly the opposite of what will happen. Something similar to (B) could happen only if the voltage source were limited in the amount of current it could provide and the small fraction of current passing through the lamp were not enough to light the lamp once the inductor dropped its resistance, or if the total current draw caused a fuse or breaker to cut off the current. However, in neither of these cases would the lamp itself \u201cburn out.\u201d<\/p>\n            <\/div>        <\/div>    <\/div><\/section>\n<\/div><br \/>\n\t<div   class='av_promobox  avia-button-no   avia-builder-el-3  el_after_av_toggle_container  el_before_av_toggle_container '>\t\t<div class='avia-promocontent'><p>\n<strong>Question 2<\/strong><br \/>\nGiven a lamp wired in a simple AC household circuit, which of the following will cause the light to dim the most?<br \/>\nA.\u00a0A capacitor wired in parallel with the lamp<br \/>\nB.\u00a0An inductor wired in parallel with the lamp<br \/>\nC.\u00a0A capacitor wired in series with the lamp<br \/>\nD.\u00a0An inductor wired in series with the lamp<\/p>\n<\/div><\/div><br \/>\n<div  class=\"togglecontainer   toggle_close_all  avia-builder-el-4  el_after_av_promobox  el_before_av_promobox \" >\n<section class=\"av_toggle_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\"  >    <div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  >        <p data-fake-id=\"#toggle-id-2\" class=\"toggler \"  itemprop=\"headline\"    role=\"tab\" tabindex=\"0\" aria-controls=\"toggle-id-2\">Answer 2<span class=\"toggle_icon\" >        <span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p>        <div id=\"toggle-id-2\" class=\"toggle_wrap \"  >            <div class=\"toggle_content invers-color \"  itemprop=\"text\"   ><p><b>D:\u00a0<\/b>You can dismiss (A) and (B), since for loads in parallel, the voltage drop is the same across all paths; the brightness of the light would not change if the lamp were wired in parallel with either a capacitor or an inductor. Loads in series, on the other hand, affect the overall resistance of the circuit and therefore the total power draw on the battery. Recall that capacitors and inductors can either let current flow freely or act as resistors, depending on the type of current. In an AC circuit, a capacitor lets current flow freely while an inductor resists current flow. An inductor placed in series with the lamp will therefore act as a resistor over which a voltage drop occurs, and the lamp will be correspondingly dimmer than if the voltage drop of the circuit occurred entirely over the lamp itself.<\/p>\n            <\/div>        <\/div>    <\/div><\/section>\n<\/div><br \/>\n\t<div   class='av_promobox  avia-button-no   avia-builder-el-5  el_after_av_toggle_container  el_before_av_toggle_container '>\t\t<div class='avia-promocontent'><p>\nWhich of the following symbols represents a polarized capacitor?<\/p>\n<p>A.<br \/>\nB. <img loading=\"lazy\" class=\"alignnone size-full wp-image-49192\" src=\"https:\/\/wpapp.kaptest.com\/study\/wp-content\/uploads\/Answer-A.png\" alt=\"Answer A\" width=\"281\" height=\"158\" \/><\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-49193\" src=\"https:\/\/wpapp.kaptest.com\/study\/wp-content\/uploads\/Answer-B.png\" alt=\"Answer B\" width=\"280\" height=\"153\" \/><br \/>\nC.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-49194\" src=\"https:\/\/wpapp.kaptest.com\/study\/wp-content\/uploads\/Answer-C.png\" alt=\"Answer C\" width=\"283\" height=\"155\" \/><br \/>\nD.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-49195\" src=\"https:\/\/wpapp.kaptest.com\/study\/wp-content\/uploads\/Answer-D.png\" alt=\"Answer D\" width=\"278\" height=\"144\" \/><\/p>\n<p>\n<\/div><\/div><br \/>\n<div  class=\"togglecontainer   toggle_close_all  avia-builder-el-6  el_after_av_promobox  el_before_av_promobox \" >\n<section class=\"av_toggle_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\"  >    <div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  >        <p data-fake-id=\"#toggle-id-3\" class=\"toggler \"  itemprop=\"headline\"    role=\"tab\" tabindex=\"0\" aria-controls=\"toggle-id-3\">Answer 3<span class=\"toggle_icon\" >        <span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p>        <div id=\"toggle-id-3\" class=\"toggle_wrap \"  >            <div class=\"toggle_content invers-color \"  itemprop=\"text\"   ><p><b>C:\u00a0<\/b>The choices represent four different capacitor symbols: a fixed capacitor (A), variable capacitor (B), polarized capacitor (C), and trimmer capacitor (D).<\/p>\n            <\/div>        <\/div>    <\/div><\/section>\n<\/div><br \/>\n\t<div   class='av_promobox  avia-button-no   avia-builder-el-7  el_after_av_toggle_container  el_before_av_toggle_container '>\t\t<div class='avia-promocontent'><p>\n<strong>Question 4<\/strong><br \/>\nA fixed resistor has a color band pattern of black, orange, orange.
