The current flowing through a conductor ...

The current flowing through a conductor and the potential difference across its two ends are as per reading of the ammeter and the voltmeter shown in (Fig. 3.50). Find the resistance of the conductor.

Text Solution

Verified by Experts

As `I = 380 mA = 380 xx 10^-3 A, V = 7.6 V`,
`R = (V)/(l) = (7.6 V)/(380 xx 10^-3) = 20.0 Omega`.

    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.
