RC CIRCUITS
1 RC CIRCUITS
An RC circuit is a circuit with a battery, a resistor and a capacitor in
series. The capacitor has a charge on it, this increases with the next
equation:
(−t/RC)
q = Q (1 − e )
Here, Q is the initial charge on the capacitor.
2 TIME CONSTANT
The time constant is equal to the RC:
RC = τ
