Function of transformer?

Question

Function of transformer??  
A. Reduce current flow  
B. Inhibit conduction  
C. Charge by proximity  
D. Increase/reduce AC voltage

Accepted Answer

Correct Answer: (D)Increase/reduce AC voltage. 
Rationale: The function of a transformer is to increase or reduce the voltage of an alternating current.A transformer operates on the principle of electromagnetic induction. It uses two coils of wire—a primary and a secondary—wrapped around a common core. When an alternating current flows through the primary coil, it creates a changing magnetic field that induces a voltage in the secondary coil. By adjusting the number of turns in each coil, the transformer can step the voltage up or down.A) Reduce current flowReducing current is not the primary function of a transformer. Any change in current occurs as a consequence of changing voltage while conserving power (approximately), according to the relationship P=VIP = VIP=VI.B) Inhibit conductionA transformer does not block or inhibit conduction. Instead, it enables efficient transfer of electrical energy between circuits through magnetic coupling.C) Charge by proximityCharging by proximity describes electrostatic induction, which is unrelated to how transformers work. Transformers rely on electromagnetic induction, not electrostatic effects.D) Increase or reduce AC voltageBy having different numbers of turns in the primary and secondary coils, a transformer can either increase (step up) or decrease (step down) the voltage of an alternating current. This is its fundamental and defining function.ConclusionTransformers are designed to change the voltage level of alternating current, either increasing or decreasing it as needed for transmission and safe use
