A `220 V` input is supplied to a transformer. The output circuit draws a current of `2.0 A` at `440 V`. If the efficiency of the transformer is `80%`, the current drawn by the primery winding of the transformer is

A 220 V input is supplied to a transformer. The output circuit draws a current of 2 A at 440 V. If the efficiency of the transformer is 80%, the current drawn by the primary windings of the transformer is

A 220 volt input is supplied to a transformer.The output circuit draws a currnt of 2.0 ampere at 440 volts If the efficency of the transformer is 80% the current drawn by the primary windings of the transformer is :

A step-down transformer is used on a 1000 V line to deliver 20A at 120V at the secondary coil. If the efficiency of the transformer is 80% the current drawn from the line is.
