Part one of term paper
A capacitor can store . Connecting it across a resistor or other device discharges it. Across the resistor there is a potential difference that creates the electric current. When the charge in the capacitor decreases, at the same time the voltage decreases. As a result the rate at which the capacitor is discharged, which is the current, is de ...

... proportional to the resistance and the square of the current that passes through it. As the energy is changed from electrical to thermal the resistor gets hot. In long distance transmission, current is reduced without reducing power by increasing voltage. The resulting lower current reduces the power loss in the power lines by keeping the current squared factor low. Long-distance transmission lines always operate at high voltage to reduce power loss. The used by many devices is the rate of energy ...
