In a transformer the number of primary turns is four times that of the secondary turns. Its primary is connected to an AC source of voltage V. Then

A transformer has 100 turns in the primary and 500 turns in the secondary. If the primary is connected to 220V DC supply, then the voltage develop across the secondary will be

A transformer has 50 turns in the primary and 100 in the secondary. If the primary is connected to a 220 V DC supply, what will be the voltage across the secondary?
