Question

write a short note on electrical energy . obtain a expression for power dissipated across a resistor.​

Answer 1

Answer:

Electrical energy is energy derived from electric potential energy or kinetic energy. ... Once converted from potential energy, electrical energy can always be called another type of energy (heat, light, motion, etc.).

Explanation:

First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 ?. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor.
