Question

Column I
Column II
(i) Fuse wires
A. Rheostat
(ii) Bulbs
B. Higher resistance
(iii) Higher power
C. Parallel
(iv) Potential divider
D. Series
(v) Lower current
E. Lower resistance​

Answer 1

Answer:

(i) → D, Fuse wire always connected in series with live wire.

(ii) → C, In household circuitrs, bulbs are connected in parallel to get the same p.d across each bulb for desired brightness.

(iii) → E, P = V2R

(iv) → A, Rheostat can also be used as a potential divider

(v) → B From Ohm’s law, I ∝ 1R.
