# Is energy produce

Answer :

No.

When a transformer steps up the voltage, the voltage increases but the current decreases in the process since the supplied power remains constant.

Now, the power is given by

where V = voltage, I = current.

Since the voltage and current increase and decrease in proportion to each other, the value of power remains constant.

Hence, energy is not produced. Energy = power x time remains constant. (Ans)
