Question

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.
.

Answer 1

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`.
