The reading of current flowing through a conductor and the potential difference its two end are shown in the ammeter and volmeter given below. What will be the value of resistance in it?

Text Solution

Verified by Experts

`I=400 mA=(400)/(1000)=0.40 A, " " V=8 " volts"`
According to Ohm's `=V=IR " " rArr " " R=(V)/(I)=(8xx10)/(4)=20Omega`

The current in a conductor and the potential difference across its ends are measured by an ammeter and a voltmeter.The meters draw negligible current.The ammeter is accurate but the vlotmeter has a zero error(that is ,it does not read zero when no potential difference is applied).Calculate the zero error if the readings for two different conditions are 1.75A, 14.4Vand 2.75a, 22.4V.
