Question # 1

When the primary of a transformer is connected to A.C mains,the current it is very small if the secondary circuit is open.Explain.

Ans 1: If the secondary circuit is open then output power will be zero,Because output power is always slightly smaller than the input power,therefore a very small value of current is being drawn by a primary coil of transformer from AC units,

Question # 1

State Faraday's law of electromagnetic induction.

Ans 1: It states that
"The average emf induced in a conducting coil of N loops is equal to the negative of the rate at which the magnetic flux through the coil is changing with time".
