AIIMS 2002 Physics Transformers Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 12
Assertion : We use a thick wire in the secondary of a step down transformer to reduce the production heat.
Reason : When the plane of the armature is parallel to the line of force of magnetic field, the magnitude of induced e.m.f. is maximum.
A
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
B
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C
Assertion is true but Reason is false.
D
Both Assertion and Reason are false.
Correct Answer
Option B
Detailed Explanation
A step-down transformer converts electrical energy from a high voltage to one at a low voltage.
