Efficiency η = Output power / input power X 100 = output power / output power + losses X 100 is the formula for a transformer’s efficiency.
The input power is known as primary power, and the output power is known as secondary power.

Efficiency η = 100W/200W X 100
Efficiency η = ½ x 100
Efficiency η = “50%”

The ability of an inductor in one circuit to induce a voltage in another is known as mutual induction. Magnetic flux envelops the conductor in a transformer primary in proportion to the amount of alternating current flowing through it.

Given that I=25A and a=3cm=9×10−2m

B=μoI/2πa

equals 4π×10−7×25/2π×3×10−2.

= 1.67 x 10-4 T

The area where the magnetic field is present or distributed is called the flux. The magnetic field flowing through a particular region or surface is referred to as the flux in the context of this question. Within the area, the magnetic field lines may vary in strength and direction, but they are always connected by a polarity. The magnetic field lines’ orientation or direction—whether north or south—is indicated by their polarity.

B is accurate because the coupling coefficient operates as illustrated below:

The force acting on a wire positioned at right angles to the magnetic field per unit current per unit length is known as the magnetic flux density (B).

There are several names for magnetic field strength, including magnetic intensity, magnetic field intensity, and magnetic field strength.

Its winding is two-phase.

Electromotive force, or EMF, is defined by Faraday’s law.

The SI unit for inductance is “Henry” (H). Both self and mutual inductance will have the same SI unit since they are both forms of inductance. Option C is therefore accurate.
