Question
A parallel plate capacitor is connected to a battery and becomes fully charged. The capacitor is then disconnected, and the separation between the plates is increased in such a way that no charge leaks off. The energy stored in this capacitor has The resistance of a wire is defined as If the current flowing through a circuit of constant resistance is doubled, the power dissipated by that circuit will What length of copper wire (resistivity 1.68 times 108 Qm) of diameter 0.15 mm is needed for a total resistance of 15 Q? When resistors are connected in parallel, we can be certain that the same current flows in each one. the potential difference across each is the same. the power dissipated in each is the same. their equivalent resistance is greater than the resistance of any one of the individual resistances. A 2.0(xF capacitor is charged to 8.0 V and then discharged through a 4.0 times 106 ft resistor. How long will it take for the voltage across the capacitor to drop to 3.0 V? A 1 .On F and a 2.0nF capacitor are connected in series across a 3.0V battery. What is the voltage across the 2.0nF capacitor? What charge appears on the plates of a 2 n F capacitor when it is charged to 100 V? If a 10uF capacitor is charged so that it stores 2.0 times 103 J of energy, what is the voltage across it?Explanation / Answer
