A transformer has 100 turns in the primary coil and 500 turns in the secondary coil. If the primary is connected to a 120 V AC source, what is the voltage across the secondary coil?
A.A) 24 V
B.D) 2400 V
C.B) 120 V
D.C) 600 V
Explanation
Core Concept
For an ideal transformer, the voltage ratio is equal to the turns ratio: V_s/V_p = N_s/N_p. Therefore, V_s = V_p(N_s/N_p) = (120 V)(500/100) = 600 V.
Correct Answer
DC) 600 V
