Question
In a standard RC circuit (shown below), a single battery is connected to a single resistor and capacitor in series.
A capacitor will discharge ---Select--- faster than at the same rate as slower than it charges.
A capacitor will charge ---Select--- slower at the same rate faster if there is no resistance.
In our RC circuit, a 4.5 V battery is connected to a 400 resistor and a 30 F capacitor. The capacitor is initially discharged when the circuit is switched on.
b) What is the time constant for this circuit?
Complete the following table for a charging capacitor. Times are given in milliseconds.

Explanation / Answer
(a)
A capacitor will discharge "at the same rate as" it charges.
A capacitor will charge "faster" if there is no resistance.
(b)
Time constant t = R*C
t = 400 * 30 * 10^-6
t = 0.012 s
