In the circuit shown in Fig. Sliding contact is moving with uniform velocity towards right. Its value at some instance is `12 (Omega)`. The current in the circuit at this instant of time will be

A

`0.5A`

B

More than `0.5A`

C

Less than `0.5A`

D

May be less (or) more than `0.5A` depending on value of 'L'

Text Solution

Verified by Experts

The correct Answer is:
B
When 'R' increases 'I' decreases so `di//dt` is-ve.
`i=(6-Ldi//dt)/(12)`
`di/dt "negative" I gt 0.5`
