Question

Two electric bulbs have resistances
in the ratio 1:2. If they are joined
in series, the energy consumed in
them is in the ratio.
(a) 2:1
(b) 1:2
(C) 4:1
(d) 1:1​

Answer 1

Answer:

Answer

Correct option is

B

1 : 2

P=I

2

R

When two resistances are connected in series, current through them is same.

Hence,

P
