How much water should you drink every day? It might not be as much as you think. Get the facts about hydration, beauty and health.
1. Battery is a source of energy for a circuit, whereas capacitor is a passive element, which draws energy from the circuit, store and release it. 2. Usually battery is a DC component, whereas capacitor is mostly used for AC applications. It is used to block DC components in circuits.
What is the potential difference across each capacitor? 10 ÂµF 20 Âµ 30 ÂµF 120V â¢ Q = CV; Q is same for all capacitors â¢ Combined C is given by: â¢ C eq = 5.46 ÂµF â¢ Q = CV = (5.46 ÂµF)(120V) = 655 ÂµC â¢ V 1 = Q/C 1 = (655 ÂµC)/(10 ÂµF) = 65.5 V â¢ V 2 = Q/C 2 = (655 ÂµC)/(20 ÂµF) = 32.75 V â¢ V 3 = Q/C 3 = (655 ÂµC)/(30 ÂµF) = 21.8 V
