 A series circuit containing a 20 uF capacitor in series with a 0.5 mega ohm resistor is

connected to a 45 V battery.

a) determine the time constant of the circuit. Ans. TC = RC = ( 20x10

-6

)( 0.5 x 10

6

) = 10 sec.

b) find the time when the voltage across capacitor is 45 volts. VC = v ( 1 + e

– t/RC

); t = infinite or

at steady state.
