Question

The ratio of secondary to the primary turns in a transformer is 3: 2 and the output power is P. Neglecting all power losses, the input power must be (A) (2P/2) (B) (3P/2) (C) (P/2) (D) P

Since losses are negligible the input power is equal to the output power.

Q. The ratio of secondary to the primary turns in a transformer is 3 : 2 and the output power is P.
Neglecting all power losses, the input power must be

$\frac{2 P}{2}$

$\frac{3 P}{2}$

$\frac{P}{2}$

P

Since losses are negligible the input power is equal to the output power.
