Question
An RC circuit is constructed with a (initially uncharged) 5.00-μF capacitor and a 5.00-ohm resistor, which are connected in series to an ideal battery with an emf of 60.0 V. At a certain time after the circuit is connected, it is found that heat is being produced in the resistor at a rate of 300 W. How much energy is stored in the capacitor at that time (in Joules)?

- None of these
- \(1.8 \times 10^4\)
- \(1.13 \times 10^{-3}\)
- \(3.75 \times 10^{-3}\)
- \(9 \times 10^{-3}\)

How much energy is stored in the capacitor at that time (in Joules)? - None of these - \(1.8 \times 10^4\) - \(1.13 \times 10^{-3}\) - \(3.75 \times 10^{-3}\) - \(9 \times 10^{-3}\)
Expert Solution
Step 1

Solution:

Given:

R = resistance of resistor = 5.00 Ω

C = capacitance of capacitor = 5.00 μF = 5.00 x 10-6 F

Vb = emf of supply battery = 60.0 V

PResistor = heat produced in resistor at time t at the rate = 300 W

Ucapacitor = energy stored in capacitor at time t in joules = ?

Choose the correct option (energies are given in joules):

  1. None of these
  2. 1.8 x 104
  3. 1.13 x 10-3
  4. 3.75 x 10-3
  5. 9 x 10-3
