- A 95-W light bulb operates on an effective ac voltage of 110 V. a) What is the effective current through the light bulb? b) From Ohm's law, what is the resitance of the light bulb?The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. CilTwo 8 awg copper conductors supply a 120v load that's located 225ft from a panelboard.
