Question 308 of 380

In a Wheatstone's bridge, there resistances P,Q\mathrm{P}, \mathrm{Q} and R\mathrm{R} connected in the three arms and the fourth arm is formed by two resistances S1\mathrm{S}_1 and S2\mathrm{S}_2 connected in parallel. The condition for bridge to be balanced will be

Show answer and solution

Answer: (C) PQ=R(S1+S2)S1 S2\frac{\mathrm{P}}{\mathrm{Q}}=\frac{\mathrm{R}\left(\mathrm{S}_1+\mathrm{S}_2\right)}{\mathrm{S}_1 \mathrm{~S}_2}

PQ=R(S1+S2)S1 S2\frac{\mathrm{P}}{\mathrm{Q}}=\frac{\mathrm{R}\left(\mathrm{S}_1+\mathrm{S}_2\right)}{\mathrm{S}_1 \mathrm{~S}_2}
