Which one of the following terms cannot represent electrical power in a circuit?

Concept:

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• V = IR -- (1)

Electric power is the rate at which electrical energy is transferred by an electric circuit. 

• The SI unit of Power is the Watt or One Joule per second.
• P = V × I -- (2)
• where, p = power, I = current, V = voltage, R = resistance

Calculation:

From equation (2), P = VI -- (3)

Now, from equation (1) and (2), P = (IR) × I = I²R -- (4)

Also, from equation (1), \(I = \frac{V}R\)

Now put the value in equation (2) then, \(P = V \times \frac{V}R\)

⇒ \(P= \frac{V{^2}}{R}\) -- (5)

From equation (3), (4), (5) P = VI = I²R = ​​\(P= \frac{V{^2}}{R}\)
