Question

Part I. A capacitor is completely charged with 610 nC by a voltage source that has 350 V.
What is its capacitance?

Now the plates of the charged capacitor are pulled apart with
the voltage source still connected.
A. The voltage drop between the plates increases.
B. The capacitance increases.
C. The charge on the plates increases.
D. The energy stored in the capacitor increases.
E. None of the above.

The initial air gap of the capacitor above was 6 mm.
What is the stored energy if the air gap is now 14 mm?

Explanation / Answer

C = Q/V = 1.74 nF V =Q/C : c) option E = (1/2)cv*v put values and get your answer
