Question

If you have a simple circuit with these components in sequence,

Power source->Capacitor->Resistor->back to power source.

The equation for the voltage change across the resistor as a function of time is VR(t)=Vps*e^-t/RC

Now if we were to swithc the sequence of the circuit to Power source->Resistor->Capacitor->back to power source.

What would the equation for the voltage change across the resistor look like now?

Select one:

a. It would be some quite different number at the time constant would change from RC to CR.

b. It would switch, as it were, with the capacitor. ?VR = ?VPS - (?VPS)(e-t/RC)

c. It would be unchanged. ?VR = (?VPS)(e-t/RC)

d. Current cannot flow across a capacitor. With not current through the resistor
Ohm's Law gives the answer, zero volts.
