Question

Which of the following statements is WRONG?

(a) when an initially charged capacitor with a capacitance C is discharged through a resistor R, the current through the resistor is always proportional to the charge of the capacitor

(b) when an initially charged capacitor with a capacitance C is discharged through a resistance R, the charge on the capacitor is reduced by a factor e is approximately 2.71 after a time interval equal to the product RC

(c) when a circuit consisting of a capacitance C (initially uncharged) and a resistance r, which are connected in series, is connected to an ideal battery with a voltage V, the ultimate charge of the capacitor is given by VC and is independent of the resistance, R

(d) when a circuit consisting of a capacitance C (initially uncharged) and a resistance r, which are connected in series, is connected to an ideal battery with a voltage V, the charge of the capacitor increases by a factor e is approximately 2.71 after a time interval equal to the product RC

(e) when a circuit consisting of a capacitance C (initially uncharged) and a resistance r, which are connected in series, is connected to an ideal battery with a voltage V, the initial current is given by V/R and is independent of the capacitance, C

Explanation / Answer

d is incorrect. the capacitor charges logarithmically.
