Compute what is the current in the primary coil

Reference no: EM13670730

A step-down transformer (turns ratio = 1:7) is used with an electric train to reduce the voltage from the wall receptacle to a value needed to operate the train. When the train is running, the current in the secondary coil is 4.12 Amp. Evaluate what is the current in the primary coil?
