Question

When a capacitor, in RC circuit, is fully charged, the current through the resistor is Select one: zero if it is the only capacitor, but maximum if there is another capacitor in series with it. At its maximum value. Greater than the current in a resistor that is farther from the battery than the capacitor. Zero. Equal to the current in a resistive circuit in parallel with the capacitor circuit.

Answer 1

Answer:

The correct option is "Zero". A further explanation is given below.

Explanation:

As we know,

The capacitor is given by:

⇒ $Q=C\times V$

Rate of change with respect to the time will be:

⇒ $\frac{dQ}{dt}=C\times \frac{dV}{dt}$

Now,

It is mentioned in the question that the capacitor is completely charged, then

⇒ $\frac{dV}{dt}=0$

i.e.,

⇒ $\frac{dQ}{dt}=0$

All other choices available aren't related to that same scenario in question. So the answer above is the perfect one.
