Given the following data, electrical power is defined as:

E = electrical energy (work)
I = current
t = time

  • A

    (P = E / t)

  • B

    (P = E / I)

  • C

    (P = I / E)

  • D

    (P = E x t)

ELECTRIC POWER
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. It is the rate of doing work.
  • Power = Electrical Work (W) / time
Electrical work (W) is performed when electrical energy is converted into another form of energy. Electrical work (W) is measured in joules (J) defined as:
  • W = U x I x t
    Where 'U' stands for voltage, 'I' is current and 't' is time.
