A transformer has 300 primary turns and 2400 secondary turns: If the primary supply voltage is 230 V, what is the secondary voltage ?

A transformer has 200 primary turns and 150 secondary turns. If the operating voltage for the load connected to the secondary is measured to be 300 V, what is the voltage supplied to the primary ?

In a transformer primary has 50 turns and secondary has 10 turns . The RMS voltage in the primary is 120V . Find the RMS secondary voltage in the open circuit .if the secondary has a load of 12 Omega . What are the currents in the primary and secondary ?

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.

A transformer has 500 turns in its primary and 1000 turns in its secondary winding. The primary voltage is 200 V and the load in the secondary is 100 2. Calculate the current in the primary, assuming it to be an ideal transformer.

A transformer has 250 primary turns and 500 secondary turns. If 200 V electric potential is applied to the primary resulting in a current of 5 mA, find the secondary voltage and current.

A step down transformer has turns ratio 40:1. (i) If the primary voltage is 240V, calculate the secondary voltage. (ii) If the secondary current is 4A, calculate the primary current.
