Question
Which of the following statement regarding transformer is incorrect?
✓
Answer
The current induced in primary circuit is of same nature as in secondary circuit with differences in amplitude only.
Explanation:
The transformer does this by linking together two or more electrical circuits using .The two coil windings are not electrically connected but are only .The difference in voltage between the primary and the secondary windings is .Also this induced voltage has the same frequency as the primary winding voltage.The current induced in primary circuit is of same nature as in secondary circuit with differences in amplitude only.A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
