Electro Magnetic Induction And Alternating Currents Question 278

Question: The turn ratio of a transformers is given as 2 : 3. If the current through the primary coil is 3 A, thus calculate the current through load resistance [BHU 2005]

Options:

A) 1 A

B) 4.5 A

C) 2 A

D) 1. 5 A

Show Answer

Answer:

Correct Answer: C

Solution:

As $ \frac{I_{P}}{I_{s}}=\frac{n_{p}}{n_{s}} $ ; i.e. $ \frac{3}{I_{s}}=\frac{3}{2}\Rightarrow I_{s}=2A $ .
