Two bulbs one of `60W` and the other of `100W` , are connected in series across a supply
(i) The current through each is same
(ii)The potential drop across `60W` bulb is more
(iii) The potential drop acorss each is the same
(iv) The current through `100W` bulb is more

Options

A. (i) only
B. (ii), (iii)
C. (i),(ii)
D. (ii) only

Answer

C

Explanation

`R_(1) = (V^2)/(60) , R_(2) = (V^2)/(100)`
`R_(1) gt R_(2)`
`V_(1) = (R_1)/(R_1+R_2) V, V_(2) = (R_2)/(R_1+R_2) V`
`V_(1) gt V_(2)`.
