In the circuit shown in figure find:

a. the current in the `3.00 Omega` resistor,b. the unknown emfs`E_1` and `E_2` and c the resistance `R`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Applying loop law in loops 1,2, and 3 we have

`E_1-12-24=0`
`:. E_1=36V`
`-E_2+24+30=0 ior E_2 =54V`
`-2R-E_1+E_2=0`
`or R=(E_2-E_1)/2`
`=9Omega`
