1.	When primary current flows, secondary circuit should be open.(a) True(b) FalseThe question was posed to me in quiz.I need to ask this question from Open Circuiting the Secondary Circuit of a Current Transformer in section Extension of Instrument Ranges of Electrical Measurements
Answer» Correct ANSWER is (b) False For EXPLANATION I would SAY: In a current transformer, even when it is not in use for any measurement PURPOSES, the secondary CIRCUIT must be closed when the primary current is flowing.
