Question

In a meterbridge experiment, the balance length is 40cm. The resistance in the gap opposite to this length of wire is 8 ohm. The resistance in the other gap is

• A. $10\Omega$
• B. $6\Omega$
• C. $4\Omega$
• D. $12\Omega$

Answer 1

Answer: (D)

$12\Omega$

$\Rightarrow \frac{4}{R}=\frac{2}{3}$
$\Rightarrow R=12\Omega$
