In the given branch `AB` of as circuit a current `I=(10t+5)A` is flowing, where `t` is time in second . At `t=0`, the potential difference between points `A` and `B(V_A-V_B)` is

A

`15V`

B

`-5V`

C

`-15V`

D

`5V`

Text Solution

Verified by Experts

The correct Answer is:
A
`I=(10t+5)A`
`(dI)/(dt)=10A//s=`constant
At `t=0, I=5A`
Now, `V_A-3xx5-1x10+10=V_A`
`:. V_A-V_B=15V`
