Question
A transformer has a primary coil with 300 turns and a
secondary coil with 150 turns. If the primary voltage is 240V, calculate the secondary voltage.Solution
The voltage ratio in a transformer is given by the ratio of the number of turns in the primary and secondary coils: VP / VS = NP / NS. Given: Primary turns (NP) = 300 turns, Secondary turns (NS) = 150 turns, Primary voltage (VP) = 240V Secondary voltage (VS) = (VP * NS) / NP = (240 * 150) / 300 = 120 volts
