In a trasnsformer, if the voltage of the primary is `V_p` and the current in the primary id `I_p` voltage in the secondary is Vs and the current Is ,write down the formulae conecting them.

A transformer without power loss carries 4000 turns in the primary and 2000 turns in thw secondary. If the primary voltage is 120 V and the current is 0.2 A . What is the current in the secondary ?

In a transformer without any loss in power , there are 5000 turns in the primary and 250 turns in the secondary. The primary voltage is 120 V and the primary current is 0.1 A. Find the voltage and current in the secondary.

The current in the secondary coil of a transformer is 1A and that in the primary is 0.5 A. If 200 V is available in the secondary coil of the transformer, what is the voltage in the primary ?

A transformer without power loss carries 4000 turns in the primary and 2000 turns in thw secondary. If the primary voltage is 120 V and the current is 0.2 A . Where are the thick wires to be used in this transformer - in the primary or secondary ? why ?
