Electro Magnetic Induction And Alternating Currents Question 258
Question: The number of turns in the primary coil of a transformer is 200 and the number of turns in the secondary coil is 10. If 240 volt AC is applied to the primary, the output from the secondary will be [BHU 1997; JIPMER 2000]
Options:
A) 48 V
B) 24 V
C) 12 V
D) 6 V
Show Answer
Answer:
Correct Answer: C
Solution:
$ \frac{V_{s}}{V_{p}}=\frac{N_{s}}{N_{p}}\Rightarrow V_{s}=\frac{N_{s}}{N_{p}}\times V_{p}=\frac{10}{200}\times 240=12\ volts $
