- The capacitor in the figure has a capacitance of 33 µF and is initially uncharged. The battery provides a potential difference of 120 V. After switch S is closed, how much charge will pass through it? Number Units Use correct number of significant digits; the tolerance is +/-2%arrow_forwardYou have a circuit with a battery hooked up to 2 capacitors in Parallel. The battery has a voltage of 4.3 V. The capacitors have a value of C1 = 40.0 µF and C2 = 25.0 u F. While finding the actual voltage is very helpful, it's hard to use this as a prediction because not all batteries are the same. So one way to look at this is a percentage. Even if the voltage of the battery is different, the percentage of the voltage should be the same regardless. Find the percentage of the battery voltage that is across capacitor 1. To find percentages: • Find the voltage across the specific capacitor just like previously Divide this voltage by the voltage of the battery • Multiply your answer by 100 to turn it into a percent Your answer should include: 2 Decimal Places Correct SI Units Your Answer:arrow_forwardA heart pacemaker fires exactly 71 times a minute.
