Which of the following terms does not represent electric power in a circuit?

By Raj Vimal|Updated : October 20th, 2022

(A) I2R

(B) IR2

(C) VI

(D) V2/R

The terms IR2 does not represent electric power in a circuit. IR2 not a circuit's electrical power source. The pace at which electrical energy is transported across an electric circuit, in units of time, is known as electric power.

Important formulas of Electric Power in a Circuit

Using the Ohm's law equation V = I × R

Where,

V is the Potential difference

R is the Resistance

I is the Current

Power:

P= V x I

also,

P= I R as V=I x R

P=V /R as I=V/R

Uses of Electricity

  • Entertainment - To watch TV
  • Engineering - Construction of structures and buildings
  • Healthcare - surgeries
  • Commercial - running of heavy machines requires electricity
  • Transport and Communication - power is required in airline travel
  • Outdoors - streetlights
  • Household - microwave, refrigerator etc
  • Space - probes and satellites
  • Office - lifts, lights, AC etc
  • Fuel - electric vehicle

Summary:

Which of the following terms does not represent electric power in a circuit? (A) I2R (B) IR2 (C) VI (D) V2/R

Electricity in a circuit is not represented by the term IR2. Not the electrical power supply of a circuit, but IR2. Electric power is the rate, measured in units of time, at which electrical energy moves across an electric circuit.
