126. A power transformer has a primary winding of 200 turns of #24 wire and a secondary winding consisting of 500 turns of the same size wire. When 20 volts are applied to the primary winding, the expected secondary voltage will be:
The secondary voltage is determined by the turns ratio. With 200 primary turns and 500 secondary turns, the secondary voltage is 20 volts multiplied by 2.5, resulting in 50 volts.
