To find the frequency of AC mains with a sonometer. WebbThe maximum value of the current that can be measured by the galvanometer is 𝐼 . Every point on the dial is thus a fraction of the current: half deflection means a current of 𝐼 2 , …
WebbIn a circuit for finding the resistance of a galvanometer by half deflection method, a 6 V battery and a high resistance of 11 kΩ are used. The figure of merit of the galvanometer 60mu A/ division . In the absence of shunt resistance, the galvanometer produces a deflection of theta = 9 divisions when current flows in the circuit. WebbClick here👆to get an answer to your question ️ 9. A simple potentiometer circuit is set up as shown in the fig. using a 1m long, uniform (3) wire AC, which has resistance of 292. The …
WebbAnswer: It is so because the deflection is made half by using a shunt resistance(S). A method of finding the internal resistance of a cell when the value is known to be high. A second cell, a galvanometer and a resistance are connected in series with the cell under test, and the value of the res...
WebbThe maximum value of the current that can be measured by the galvanometer is 𝐼 . Every point on the dial is thus a fraction of the current: half deflection means a current of 𝐼 2 , quarter deflection is 𝐼 4 , and so on.. We ideally want to add a certain amount of resistance to the galvanometer, such that the total resistances make the current 𝐼 .
WebbUse of Shunt in Galvanometer. The shunt is an electrical conductor joining two points of a circuit, through which more or less of a current may be diverted. It is a device which allows electric current to pass around another point in the circuit by creating a low resistance path. In order to convert a Galvanometer into an Ammeter, a very low resistance known … denver ban red light camerasWebb20 dec. 2024 · The resistance of the given galvanometer as found by half deflection method .
