Question

If 420 J of energy are absorbed by a resistor in 7 min, what is the power to the resistor?

Answer 1

1 Watt

Power= Energy/time = E/t

it is the mechanical power equation.

This formula states that the consumption of energy per unit of time is called power.

In the question,

Energy = 420 J

Time = 7 mins = 420 secs

Applying the formula

E/t the power comes out to be 1 watt.

So, the answer to the question is 1 Watt.
