In the circuit shown below, the current that flows from `a` to `b` when switch `S` is closed is

A

`- 1.5 A`

B

`+ 1.5 A`

C

` + 1.0 A`

D

`- 1.0 A`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) After closing the switch, `5 Omega` will be shorted.
`I = (10)/(10) = 1 A rarr` This is from `b` to `a`
So current from `a` to `b = - I = - 1 A`
