Question

A resistor with 760 is connected to the plates of a charged capacitor with capacitance 4.12uF . Just before the connection is made, the charge on the capacitor is 9.00mC.

PartA:

What is the energy initially stored in the capacitor?

Uo=           ?J

PartB:

What is the electrical power dissipated in the resistor just after the connection is made?

P0=        ?W

Part C:

What is the electrical power dissipated in the resistor at the instant when the energy stored in the capacitor has decreased to half the value calculated in part (A)?

P=     ?W
