WebThe principle of the Wheatstone bridge is followed by a metre bridge for its efficient working. 6) Which material wire is used in a metre bridge? The materials such as nichrome, constantan or manganin are used in making the wire of a metre bridge because these materials have a high value of resistance, and the coefficient of the temperature of their … WebMar 2, 2024 · Meter bridge is used to measure the value of unknown resistance, It is based on the principle of Wheatstone bridge i.e. when the bridge is balanced then \[\dfrac{P}{Q}=\dfrac{R}{S}\]. Where P= resistance of wire AB, Q= resistance of wire BC. So correct option is A.Wheatstone Bridge Additional Information:
Wheatstone Bridge Working Principle, Construction, Formula And …
WebThe Wheatstone bridge is a very sensitive device; therefore, it is possible that the measurements using a Wheatstone bridge may not be precise in an off-balance condition. Wheatstone bridge usually measures resistances that are in limited ranges from a ohms to kilo-ohms which means that for high resistance measurements, the galvanometer is … WebApplications of Wheatstone Bridge. The Wheatstone Bridge has many uses in electronic circuits other than comparing an unknown resistance with a known resistance. When used with Operational Amplifiers, the Wheatstone bridge circuit can be used to measure and amplify small changes in resistance, RX due. Wheatstone bridge is not suitable for ... tenda u0
Wheatstone bridge: concept and application - Khan Academy
WebWheatstone bridge principle states that if four resistances P, Q, R and S are arranged to form a bridge as shown in the fig. below with a cell E and one way key, put between the points A and C and a galvanometer is connected in between the points B and D such that there is no current through G. The balance point is obtained when, galvanometer shows … WebThe Wheatstone bridge working principle is null deflection. The condition of null deflection is the ratio of the known resistances should be equal and that no current should flow through it, i.e., no deflection in the galvanometer. Before working on it, we have to prepare the Wheatstone bridge. In normal conditions, it remains in an unbalanced ... tenda u10
