If charge flown through a wire is given ...

If charge flown through a wire is given by `q=3sin(3t)`, then
Q. Find out the current flown through the wire at `t=(pi)/(9)` second.

A

`4.5 Amp`

B

`4.5sqrt(3)Amp`

C

`sqrt(3)//sqrt(2)Amp.`

D

`9 Amp`

Text Solution

Verified by Experts

The correct Answer is:
A
`i=(dq)/(dt)=3xx3cos(3t)rArri|_(t=(pi)/(9))=9cos(3.(pi)/(9))`
`=9cos((pi)/(3))=(9)/(2)A`
