Question:

A 7.0 kW resistor is in parallel with a 8.4 kW resistor. This parallel portion of the circuit is in series with a 10.0 V capacitor and a 780 mF capacitor.

a) you replace the two resistors with a single resistor that will give the same effect. What does this new circuit look like and what is the value of the resistor?

b) How long will it take the capacitor to charge to 50% of its maximum?

c) At this time, what will the voltage across the capacitor be?


Answers

Answer:- Ri=7kn, R2 = 8.4kor, &=lov, c= 780 nF kr (a) The value of resistor (R)= - 3 PIRL - (7) (8-4) k2 . R+R2 -= 3.82 7+84
