Write any two factory responsible for energy losses in actual transformers.
Two factors responsible for energy losses in actual transformers are: Core Losses: Due to hysteresis and eddy currents in the core material, resulting in heat generation. Copper Losses: Caused by the resistance of the windings, which generates heat when current flows through them. For more visit herRead more

When a lamp is connected to an alternating voltage supply, it lights with the same brightness as when connected to a 12 V d.c. battery. what is the peak value of alternating voltage source?
When the lamp connected to an alternating voltage supply lights with the same brightness as when connected to a 12 V DC battery, the RMS value of the AC voltage is 12 V. The peak value (V peak ) is √2 × 12 ≈ 16.97V. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/Read more

Which physical quantity remains unchanged in a transformer?
In a transformer, the power (ideally) remains unchanged. The input power in the primary winding is equal to the output power in the secondary winding, assuming no energy losses (ideal transformer condition).

The susceptibility of a magnetic material is – 4.2 × 10⁻⁶. Name the type of magnetic materials it represents.
The susceptibility of −4.2 × 10-⁶ indicates that the material is diamagnetic. Diamagnetic materials have a small negative susceptibility, meaning they are weakly repelled by a magnetic field and do not retain magnetism.

What should be the orientation of a magnetic dipole in a uniform field so that its potential energy is minimum (or the dipole is in stable equilibrium)?
The potential energy of a magnetic dipole in a uniform magnetic field is minimum (stable equilibrium) when the dipole aligns parallel to the field, with its magnetic moment (m) pointing in the same direction as the field (B).
