In the arrangement the current through `5 Omega` resistor is

A

`2A`

B

zero

C

`(12)/(7)A`

D

`1A`

Text Solution

Verified by Experts

The correct Answer is:
a
The equivalent circuit The equivalent emf of the two parallel cell is
`epsilon_(eq) = 12V`

Total resistance of the circuit
`R_(t) = 5+(2xx2)/(2+2) = 6 Omega`
Current , `I = (epsilon_(eq))/(R_(t)) = (12)/(6) = 2A`
