Question

If R1 and R2 be the resistance of the filament of 40 W and 60 W respectively operating 220 V, then
(i) R1 < R2
(ii) R2 < R1
(iii) R1 = R2
(iv) R1 >= R2

Answer 1

Answer:

I think it would be"(ii)R2<R1"

Answer 2

Explanation:

Aloha !

If we have two resistance in the circuit .

Sum of them is 100w

P¹×R¹=P²×R²

220×40=P²×60

8800=P²×60

P²=146.66

Therefore R¹>R²
