For the given circuit, comment on the type of transformer used.
Show Hint
- Auxiliary transformer
- Step down transformer
- Step-up transformer
- Auto transformer
The Correct Option is C
Solution and Explanation
Secondary voltage: \(V_2 = \frac{P}{i_L} = \frac{60}{0.11} = 545\ \mathrm{V}\).
Since \(V_2 \gt V_1 = 220\ \mathrm{V}\), the transformer steps the voltage up (with separate primary and secondary coils, so not an auto transformer).
Answer: (3) Step-up transformer

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
