Question

Match List - I with List - II.

List - I	List - II
A. Three Phase Induction Motor B. Three Phase Alternator C. Transformer D. Single phase Induction Motor	I. Constant Frequency II. Not self starting III. Always runs at less than synchronous speed IV. Always runs at synchronous speed

• A. A-III, B-IV, C-I, D-I
• B. A-III, B-IV, C-I, D-II
• C. A-IV, B-III, C-I, D-II
• D. A-IV, B-II, C-III, D-I

Hint:

Important machine properties: \[ \text{3-}\phi \text{ induction motor} \rightarrow \text{speed below } N_s \] \[ \text{Alternator} \rightarrow \text{synchronous speed} \] \[ \text{Single phase induction motor} \rightarrow \text{not self starting} \]

Answer 1

The Correct Option is B
