DC measuring instruments are based on magnetic effect of current, whereas AC measuring instruments are based on heating effect of current. Now, match entries of Column I with entries of Column II with their correct proportionality.
Column I | Column II | ||
A. | Deflection of AC ammeter | I. | V |
B. | Deflection of DC ammeter | II. | V2 |
C. | Deflection of AC voltmeter | III. | I |
D. | Deflection of DC voltmeter | IV. | I2 |
Choose the correct answer from the options given below.

For a DC ammeter or voltmeter, a moving coil galvanometer is used. So, deflection of 
For an AC ammeter or voltmeter, a hot wire deflection instrument is used.
Hence, A-IV, B-III, C-II, D-I.
