Please show all steps for further problem solving. thankyou,
A 20µF capacitor is connected in series with an unknown resistor.The capacitor is initially charged to 50V. The voltage drops to 10Vafter 8.0ms . Find the unknown resistance.
Answer is 249ohms. How do you get it? Steps?
I think you have to use one of these equations: wheree the sub0means intial
Q(t) = Q(sub0)e^(-t/t)
where t = RC and is time constant
I = I(sub0)e^(-t/t)
