The resistance of a conducting wire is 1...

The resistance of a conducting wire is 10 `Omega`. If a battery of 1.5 V is connected to it, the electric current flowing through it will be ………………….. .

A

0.15 mA

B

1.5 mA

C

15 mA

D

150 mA

Text Solution

Verified by Experts

The correct Answer is:
D

`R = V/I`
`:. I = V/R = 1.5/10 =0.15`
`=150 xx 10^(-3)`
`=150 mA`
