An 12µF capacitor is connected in series to a 0.5M? resistor across the dc voltage supply of 240V.
verify:
(a) Time constant
(b) Initial charging current
(c) Time for capacitor voltage increase to 150V
(d) The current flowing through the capacitor after 4 seconds
(e) Energy stored in the capacitor when it is fully charged
(f) Sketch the current and voltage (IV) curve to show the process of charging the capacitor.
