The power along the circuit is calculated through the equation,
                               P = I x R²
where P is power in Watts, I is current in ampere, and R is resistance is Ohms. Substituting the known values from the given,
                              P = (6.0 A) x (5 ohms)² = 150 Watts
Thus, the power generated in the circuit is equal to 150 W. 

Answer;

180 watts

Explanation;

  • Power represents the work done per unit time.
  • Thus; power = work done/time
  • Power is measured in J/s or watts.
  • Power = Heat energy/time
  • But heat energy = I²Rt, where I is the current, R is the resistance, and t is time in second.

Thus, power = I²Rt/t

                    = I²R

Therefore; power = 6²× 5

                             = 180 Watts
