What is the ratio of power consumed in resistances `R_(1) and R_(2)` as shown In figure ?

A

`1: 4 `

B

`4 : 1`

C

`1: 2`

D

`2: 1`

Text Solution

Verified by Experts

The correct Answer is:
A
`1: 4`
I = `(10)/(2 + 8) = (10)/(10) ` = 1 A
`P_(1) = I^(2) R_(1) and P_(2) = I^(2) R_(2)`
`(P_(1))/(P_(2)) = (R_(1))/(R_(2)) = (2)/(8) = (1)/(4)`
