In a stap-up transformer, if ratio of turns of primary to secondary is 1 : 10 and primary voltage is 230 V. If the load current is 2 A, then currect in primary is

In a stepup transformer, the ratio of number of turns in primary and secondary coils is 1 : 10 . What voltage will develop in the secondary if the primary is connected to 220 V mains ? If the current drawn from the secondary is 2A, calculate the current through the primary

The transformer ratio of transformer is 10 : 1 . If the primary voltage is 440 V , secondary emf is

In a transformer, the number of turns in primary and secondary are 500 and 2000 respectively. If current in primary is 48A , the current in the secondary is

A transformer has 500 turns in the primary and 1000 turns in its secondary. The primary voltage is 200 V and load in secondary is 100 ohm. Calculate the current in primary assuming it to ideal transformer.

In an ideal transformer, the number of turns in the primary is 120 and that in the secondary is 240. what is the secondary current if the primary current is 6A ?

In a transformer, the number of turns in primary coil and secondary coil are 5 and 4 respectively. If 240 V is applied on the primary coil, then the ratio of current in primary and secondary coil is
