Electro Magnetic Induction And Alternating Currents Question 241
Question: What is increased in step-down transformer [MP PMT/PET 1998; CPMT 1999]
Options:
A) Voltage
B) Current
C) Power
D) Current density
Show Answer
Answer:
Correct Answer: B
Solution:
We know that for step down transformer $ V_{p}>V_{s} $ but $ \frac{V_{p}}{V_{s}}=\frac{i_{s}}{i_{p}};\ \ \therefore i_{s}>i_{p} $ Current in the secondary coil is greater than the primary.
