Lecture 21, ACT 3
The primary coil of an ideal transformer is connected to an AC voltage source as shown. There are 50 turns in the primary and 200 turns in the secondary.
- If V1 = 120 V, what is the potential drop across the resistor R ?
The ratio of turns, (N2/N1) = (200/50) = 4
The ratio of secondary voltage to primary voltage is equal to the ratio of turns, (V2/V1) = (N2/N1)
Therefore, (V2/V1) = 480 V
