Question # 1
What is the function of soft iron core in transformer?
Question # 2
A power supply needs 500 W which will be given by a transformer. If 240 V is applied at the primary coil of transformer, how much current will be induced in secondary? The turn ratio is 1:3 and assume that it is an ideal step down transformer.
Question # 3
What is the source of electrical connection between primary and secondary coils of a transformer?
Question # 4
There are 200 turns in primary coil and 75 turns in secondary coil of a transformer. If 400 V alternating voltage is applied to the primary, what will be the voltage at secondary?
Question # 5
The turn ratio of a step down transformer is 1:20. If 12 V is required at secondary as output, how much voltage must be applied on primary of transformer?
