In a meter bridge experiment, resistance box (with R = 2 Ω) is connected in the left gap and the unknown resistance S in the right gap. If the balancing length be 40 cm, calculate the value of S
Using the meter bridge formula R/S = L1/(100 – L1), we substitute R = 2Ω, L1 = 40 cm: 2/S = 40/60
Solving, S = 3Ω.
Correct answer: (b) 3Ω.
