The term IR2 does not represent electric power in a circuit. IR2 is 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 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?
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.
