RC Circtuit with Expulsion = 12.0 votes

Consider an RC circuit with epsilon = 12.0 V, R = 175 ohms, and C = 55.7 micro-F. Find (a) the time constant for the circuit, (b) the maximum charge on the capacitor, and (c) the initial current in the circuit.

Solution Preview

The time required to charge a capacitor to 63 percent (actually 63.2 percent) of full charge or to discharge it to 37 percent (actually 36.8 percent) of its initial voltage is known as the TIME CONSTANT (TC) of the circuit.

The value of the time ...

Solution Summary

The value of the time constant in seconds is equal to the product of the circuit resistance in ohms and the circuit capacitance in farads.
