Question

In an Induction motor, the rotor copper loss is equal to

• A. Slip \(\times\) rotor input power
• B. \((1-\text{slip})\times\) rotor input power
• C. Rotor input power/slip
• D. Slip\(^2\times\) rotor input power

Hint:

In an induction motor, rotor copper loss \(=sP_2\), and mechanical power developed \(=(1-s)P_2\).

Answer 1

The Correct Option is A
