NEET Physics AC Voltage Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Induced emf in secondary (i) N_s turns (b) Magnetic flux linkage (ii) d(φ)/dt (c) Back emf in primary (iii) N_p turns (d) Voltage across capacitor (iv) v_m sin(ωt)
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The induced emf in the secondary of a transformer is proportional to the number of turns in the secondary (N_s) and the rate of change of magnetic flux (d(φ)/dt). The back emf in the primary is also related to the number of turns (N_p) and the same principle of flux change applies. The voltage across a capacitor in an AC circuit is represented by v_m sin(ωt).
