Reference no: EM131058679

A transformer has 4500 turns on a primary coil turns 30,000 turns on the secondary coil. If the secondary coil shows 2.5A of current under 400V and is 100% efficiency find the voltage and current of the primary coil

If the new efficiency drops to 80% what is the new primary power if the output power on secondary coil is 10,000 W
