Problem: A pair of 10μF capacitors in a high-power laser are charged to 1.7 kV.a. What charge is stored in each capacitor?b. How much energy is stored in each capacitor?

FREE Expert Solution

The charge stored by a capacitor:

Q=CV

Energy stored in a capacitor:

U=12CV2

(a)

C= C2 = 10μF (10-6F/1μF)= 10 × 10-6 F

V1 = V2 = 1.7 kV(1000V/1kV) = 1700 V
