Answer 1

Answer:

5,400J

Explanation:     W.K.T      Q=I^2RT

                                    GIVEN   R=5 Ω, I=3A, T=2min=120sec

                                                Q= 3^2*5*120

                                                Q=5,400J            

Answer 2

Given - Resistance, current and time

Find - Heat energy

Solution - Heat energy produced is 5400 Joules.

Heat energy = current²*resistance*time

Time = 2*60

Performing multiplication

Time = 120 seconds.

Heat energy = 3²*5*120

Taking square and performing multiplication

Heat energy = 5400 Joules

So, the heat energy is 5400 Joules.
