In the circuit shown in figure, `E_1 and E_2` are tow ideal sources of unknown emfs. Some currents are shown. Potential differences appearing across resistance is `V_A - V_B = 10V.`

A

The current in the CD branch is 5 amp

B

The unknown emf `e_(1)` is 40 volts

C

The unknown emf `epsilon_(2)` is 68 volts

D

The unknown resistance `R` is `9Omega`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
By applying Kirchhof's law
`epsilon_(1)=40V`
`epsilon_(2)=68V`
`R=9Omega` and current through `4Omega=5` amp
