Question

The ratio of turns in the transformer is given as 2:3. If the current passing through the primary coil is 3 A. Find the current through the load resistance:

• A. 4.5 A
• B. 1.5 A
• C. 2 A
• D. 1 A

Answer 1

The correct option is A 4.5 A

The ratio of turns in secondary winding to primary winding is $2:3$

The current in primary coil is $3A$

Let the current in secondary coil be $I$

We have $\frac{I}{3}=\frac{3}{2}$

$\Rightarrow I=\frac{9}{2}=4.5$

Therefore the correct option is $A$
