Homework Statement
A capacitor is in this device is charged 6.10KV and stores 1140 J of energy. What's the capacitance?
Homework Equations
W= 1/2 Q Delta V
The Attempt at a Solution
PE is W
W= 1140 J
Delta V: 6.10 KV
Q =?
C=?
Delta V = -W/Q rewrite to Q= -W/Delta V
convert kV to V
Q= -1140/6100V= -.18
then C= Q/V -.18/6100= -3.06E -5
