Wheatstone Bridge & Metre Bridge
With resistance in the left gap and resistance in right gap of a meter bridge, the balance point is obtained at cm from left end. In what way and to which resistance resistance be connected to obtain the balance point at cm from the left end?
Show answer and solution
Answer: (c)
- Balance at 50 cm needs equal gap resistances.
- : put in series with .
- So the answer is (c) in series with .
