1 ohm resistance is in series with a Ammeter which is balanced by 75 cm of potentiometer wire. A standard cell of 1.02 V is balanced by 50 cm.t he ammeter shows a reading of 1.5 A. The error in the ammeter reading is

A

0.002 A

B

0.03 A

C

1.01 A

D

no error

Text Solution

Verified by Experts

The correct Answer is:
B
`1.02Vto50cm`
`?to75cm`
`V=(75xx1.02)/(50)=1.53`
error `=1.53-1.5=0.03`
