SATHEE: Electro Magnetic Induction And Alternating Currents Question 241

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 $\frac{V_{p}}{V_{s}} = \frac{i_{s}}{i_{p}}; ∴ i_{s} > i_{p}$ Current in the secondary coil is greater than the primary.
