When two electric bulbs of 40W and 60W are connected in parallel, then the:

A

200 W bulb will glow more

B

60 W bulb will glow more

C

100 W bulb will glow more

D

All the bulbs will glow equally

Text Solution

Verified by Experts

The correct Answer is:
A
In parallel, `P prop 1/R` and `H prop 1/R`
`P_(4) =(6)^(2)/4 = 9W`

If three bulbs 60 W , 100 W and 200 W are connected in parallel, then

There are two electric bulbs of 40 W and 100 W . Which one will be brighter when first connected in series and then in parallel,

There are two electric bulbs of 40 W and 100 W . Which one will be brighter when first connected in series and then in parallel ?

Assertion : Two electric bulbs of 50 and 100 W are given. When connected in series 50 W bulb glows more but When connected parallel 100 W bulb glows more . Reason : In series combination, power is direclty proportional to the resistance of circuit. But in parallel combination, power is inversely proportional to the resistance of the circuit.
