A TRANSFORMER is a device that transfers electrical energy from one circuit to another by
electromagnetic induction (transformer action). Voltage induced into the secondary from the primary is
determined by the turns ratio.
Turns ratio formula:
Turns and current ratios:
By dividing both sides of the equation by IpNs, you obtain:
