The step-down transformer in a local neighborhood reduces


The step-down transformer in a local neighborhood reduces the voltage from a 7,200 Volt line to 120 Volt.

(a) If there are 125 loops on the secondary, determine how many are on the primary coil?

(b) Determine what current does the transformer draw from the line if the current in the secondary is 36 Amp?

(c) Determine what are the power input and output?
