Question

a 10 micro farade capacitor in series with an 1M ohm resistor is connected across 100 v DC supply determine the voltage across the capacitor 3 sec afeter switch on​

Answer 1

Answer:

The equation for voltage versus time when charging a capacitor C through a resistor R, is: V(t)=emf(1−et/RC) V ( t ) = emf ( 1 − e t / RC ) , where V(t) is the voltage across the capacitor and emf is equal to the emf of the DC voltage source.
