WebIn the meter bridge, the null deflection is shown on the galvanometer which is at a distance of 30 cm from one point. When a known resistance of 10 Ω is connected in parallel with another unknown resistance S the null … WebAns: It is called a metre bridge because the bridges use one-meter long wire. Q2. What is the null point? Ans: Null point is defined as the point at which a galvanometer reads 0 deflections. Q3. Why is the bridge method better than the Ohms law of measurement? Ans: Bridge method is better than the Ohms law of measurement because of the null ...
