An ideal transformer is used to step up an alternating emf of 220V to 4.4kV to transmit 6.6kW of power The current rating of the secondary is

A power transformer is used to step up an alternating emf of 200V to 4 KV and to transmits 5KW power. If the primary is of 1000 turns, calculate, assuming the transformer to be ideal. (i) The number of turns in the secondary (ii) The current rating of the secondary

A transformer is used to step up an alternating emf of 200V to 440V. If the primary coil has 1000 turns, calculate the number of turns in the secondary coil.

An ideal transformer converts 220 V AC to 3.3 kV AC to transmit a power of 4.4 kW. If primary coil has 600 turns, then alternating current in secondary coil is

An ideal transformer converts 220 V AC to 3.3 kV AC to transmit a power of 4.4 kW. If primary coil has 600 turns, then alternating current in secondary coil is

An ideal transformer converts 220V a.c. to 3.3kV a.c. to transmit a power of 4.4kW . If primary coil has 600 turns, then alternating current in secondary coil is
