Question

In an electrical circuit, "_____" refers to the rate at which electrical energy is transformed into another kind of energy.

Answer 1

Answer:

Electrical power

Explanation:

Electrical power: Electric power (P) is defined as the energy (W) used or produced or transformed per seconds.

Power = Energy produced/transformed/time taken.

P = W/t................................ Equation 1

Where t = time taken

But,

W = VIt................................ Equation 2

Substituting equation 2 into equation 1

P = VIt/t

P = VI............................ Equation 3

or

P = V²/R or P = I²R.

The unit of power is J/s or Volt-ampere is called watt (W).

Large amount of electric power are required in the industry

1 kW = 1000 W

1 MW = 1000000 W

1 h.p = 3/4 kW.
