If the cell of emf 5 volt shown in the figure gives a power of 10W. Q, find the powers consumed by the resistors `2 Omega` and `1 Omega`

`2W, 18W`

`8W, 49W`

`8W, 18W`

`2W, 49W`

Text Solution

Verified by Experts

Since the cell gives out a power of `10W` , a current `2A` must flow through the cell towards left.
`:.` Power consumed in `2Omega` resistor `=2^(2)xx2=8W`
Total current flowing `1Omega=7Amp` .
`:.` Power consumed by `1Omega=7^(2)xx1=49W`
