Question

A television that is 83% efficient provides 4 600 J of useful energy. How much energy does it consume?

Answer 1

Total energy consume will be equal to 5542.175 j

Step-by-step explanation:

We have given efficiency of the television is 83% = 0.83

Now it is given that useful energy is 4600 joule

We have to find the total energy consume

We know that efficiency is equal to ratio of useful energy to total energy consume

So 0.83 = 4600/total energy consume

total energy consume = 5542.175

So total energy consume will be equal to 5542.175 J
