Charge passing through a conductor carry...

Charge passing through a conductor carrying current is given by Q = `5t^(2) + 3t +1`, How much amount of current will pass in t = 5 s ?

A

9A

B

49 A

C

53 A

D

151 A

Text Solution

Verified by Experts

The correct Answer is:
C
53 A
I = `(dQ)/(dt ) = 10 `By taking t = 5 in t + 3
I = 53 A
