DC TRANCIENTS:

i): Charging a capacitor:

Example 1:

A 4µ capacitor in series with a 100k? resistor is to be charged by being connected to a 200V dc source.

Find:

i). The time constant

ii). Initial charging current.

iii). Initial rate of growth of p.d. across the capacitor

iv).p.d across thee capacitor after a time equal to 1 time constant.

v) .the time taken for the capacitor voltage to reach 18V.
