A 100 µF capacitor is charged to 50 V.  It is then connected across a 220 kΩ resistor.  Calculate the time need to discharge the capacitor to 10 V.

1. Determine the charge and voltage across each capacitor in the following circuit, assum- ing that the battery has been connected for a long period of time. 6.0 nF 1.0 nF 3.0 nF 5.0 NF 3.0 nF 12.0 V 4.0 nF

The energy required to charge a 10 µF capacitor to 100 V is a) 0.1 J b) 0.05 J c) 5 x 10(-9) d) 10 x 10(-9) J

Three capacitors 10 µF, 20 µF, 30 μF are connected in series across 150V (sinusoidal). Then identify the correct statement Maximum voltage will be applied across 10 µF Maximum voltage will be applied across 30 µF Maximum voltage will be applied across 20 µF Minimum voltage will be applied across 10 µF
