In a meter bridge experiment the ratio
WebAt this point, the bridge is said to be balanced. CALCULATION: Given: In first case balance point is at 25 cm from the zero end According to the Wheatstone bridge principle (which is the foundation of meter bridge), ⇒ R S = P Q For the first balanced bridge situation, ⇒ R S = P Q = 25 75 = 1 3 where R and S are the two unknown resistances WebA metre bridge, also known as a slide wire bridge, is an instrument that works on the principle of Wheatstone bridge. It is used to determine the unknown resistance of a conductor. Below is an experiment on how to find the resistance of a given wire using a metre bridge and to determine the resistivity of its material. Table of Contents: Aim

WebJan 2, 2024 · With resistances X and Y ohm in left and right gaps respectively of a metre bridge, the point is obtained at 30 cm from the left of the wire. When Y is shunted with 15 Ω resistance, the shift in null point is 10 cm. Solution: Case – I: Given: resistance in left gap = X Ω, Resistance in right gap = Y Ω, l = 30 cm and, 100 – l = 100 – 30 = 70 cm
