State the meaning i. ohmic conductors, ii. electric power, iii. electrical energy

i. Ohmic conductors: Ohmic conductors are materials that have a linear relationship between the applied electric field and the resulting electric current. This means that the electric current through an ohmic conductor is directly proportional to the applied electric field. Ohmic conductors obey Ohm’s law, which states that the electric current through a conductor is equal to the applied voltage divided by the resistance of the conductor. Examples of ohmic conductors include metals such as copper and aluminum.

ii. Electric power: Electric power is a measure of the rate at which electrical energy is transferred or consumed. It is typically measured in watts (W) and is calculated by multiplying the voltage and the current in an electrical circuit. Electric power is an important parameter in electrical engineering, as it determines the amount of electrical energy that can be transferred or consumed in a given time.

iii. Electrical energy: Electrical energy is the energy that is associated with the movement of electric charges. It is a form of energy that can be stored in electrical devices such as batteries and capacitors, and it can be transferred from one place to another through electrical circuits. Electrical energy is typically measured in joules (J) and is calculated by multiplying the electric power by the time for which the power is applied.
