While taking a bath, a person touches the metal case of a radio. The path through the person to the drainpipe and ground has a resistance of 4460 Ω. What is the smallest voltage (in V) on the case of the radio that could cause ventricular fibrillation?

The figure below shows a capacitor, with capacitance C = 35.0 μF, and a resistor, with resistance R = 40.0 kn, connected in series to a battery, with = 13.0 V. The circuit has a switch, which is initially open. + R (a) What is the circuit's time constant (in s)? (b) After the switch is closed for one time constant, how much charge (in C) is on the capacitor?

Let's say you have a 30W lightbulb that operates on a 120V alternating current. When the light is on the temperature is 2473 celsius. What would be the resistance at 2066 celsius? Note that the temperature coefficient α=4.5x10^-3/celsius

A fully charged RC circuit is set up using R = 15.0 Ω and C = 8.20 μF with the switch initially open, as shown in the figure. At a certain time after the switch is closed, the current in the circuit has magnitude 3.00 A and the charge on the capacitor is 30.0 μC. At this time, what is the rate at which energy is being stored in the capacitor (in W)?
