Consider the RC circuit in the figure below. The switch was at position a for a long period of time and is switched to position b at time t = 0. For the following, check each box that corresponds to a true statement. Select "None of the above" if none of them are true.
Consider the RC circuit in the figure below. The switch was at position a for a long period of time and is switched to position b at time t = 0.
For the following, check each box that corresponds to a true statement. Select "None of the above" if none of them are true.
A. Immediately after the switch is moved to b, the voltage across the capacitor is not zero.
B. The current through the resistor and the current 'through' the capacitor are always the same.
C. If the switch has been at b for a while, and we then move it to a, the charge on the capacitor as a function of time will look like an exponential decay.
D. If the switch has been at a for a while and we then switch it to b, the current through the resistor as a function of time will look like an exponential decay.
E. While the switch is at a (having been at a for a while), the current 'through' the capacitor is zero.
F. Immediately after the switch is moved to b, the voltage across the resistor is zero.
G. None of the above.
