Question

Two resistances 2 ohm and 3

ohm are connected across the two gaps of the metre bridge as shown in figure. Calculate the current through the cell when the bridge is balanced and the specific resistance of the material of the metre bridge wire. Given theresistance of the bridgewire is 1.49 ohm and its diameter is 0.12 cm.​

Answer 1

$\huge\star\mathfrak\pink{{Solution}}$

When the bridge is balanced, the resistances 2 and 3 ohm are in series and the total resistance is 5 ohm.

Let R1 be the resistance of the wire =1.49 Ω, and R2 be the total resistance (2+3)=5 Ω
