Two 500μF capacitor are connected in parallel, and then to a 100kW (105W) resistor.
The capacitors are momentarily charged using a 1000V D.C. supply.
Find:
a) The time constant of the circuit.
b) The time “t” taken for the capacitor voltage to decay to 630 volts
c) The current in the resistor at t = 0 and t = 5 seconds
a)Is the time constant =RC=100s?
b)Do i use V=Vmax(e^(-t/RC))=99.43s?
c) do i use V=Vmax(e^(-t/RC)) again so for 0s its 0.01Amps and for 5s 0.095Amps?
