Question
3.) Find the charge on the positive plate when the capacitor is fully charged.
4.) How much energy is stored in the fully charged capacitor?
after points a and d are joined? 3.) Find the charge on the positive plate when the capacitor is fully charged. 4.) How much energy is stored in the fully charged capacitor? after points a and d are joined? 2.) What is the magnitude of the voltage across the capacitor at the instant 1.) What is the magnitude of the current flow to the capacitor at the instantExplanation / Answer
2) ZERO
1) current = 3/2*103 = 1.5*10-3 A (ans) or 1.5 mA (ans)
3) charge Q = CV =1500*3*10-6 = 4500 *10-6C (ans) or 0.0045 C (ans)
4) Energy = 0.5 CV2 = 0.5*1500*10-6 *9 = 6750 *10-6 Joules (ans) or 6.750 mJ(ans)
