Q68 / 90 · JEE Main 2021 (16 Mar Shift 2) · Physics

For the given circuit, comment on the type of transformer used :

A
Auxilliary transformer
B
Auto transformer
Correct answer
C
Step-up transformer
D
Step down transformer

Solution

$V_{S} = \frac{P}{i} = \frac{60}{0.11} = 545.45$

$V_{P} = 220$

$V_{S} > V_{P}$

$\Rightarrow$ Step up transformer

Hence, the correct answer is option: 'C'.
