Fourty electric bulbs are connected in series across a 220 V supply. After one bulb is fused the remaining 39 are connected again in series across the same supply. The illumination will be
-
- more with 40 bulbs than with 39
- more with 39 bulbs than with 40
- equal in both the cases
- in the ratio 40² : 39²
Correct Option: B
Since, the voltage is same for the two combinations, therefore H∝(1/R).. Hence, the combination of 39 bulbs will glow more.
