Question on: WAEC Physics - 2014
A transformer has 400 turns of wire in the primary coil and 40 turns in the secondary col. If the input voltage is 150 volts. Calculate the magnitude of the output voltage
A
150V
B
55V
C
36V
D
15V
Ask EduPadi AI for a detailed answer
Correct Option: D
\(\frac{ES}{EP} = \frac{Ns}{Np} = \frac{Es}{150} = \frac{40}{400}\)
Es = \(\frac{150 \times 40}{400}\)
= 15V
Es = \(\frac{150 \times 40}{400}\)
= 15V
