WebNo, galvanometer cann't be used for measuring current as it is very sensitive instrument, even for small value of current it gives full scale deflection. Galvanometer can be used in series connection for measuring current, it has large resistance. So, the value of current will not be accurately measured. Previous Question Next Question WebA galvanometer is an electronic measuring device. It used magnetism to measure changes in electricity. It was the leading instrument for this purpose from its invention in 1820 until the past few decades when electronic instruments have largely replaced it.

Web21 jan. 2024 · Question 38 Explain how a galvanometer works. Answer: A galvanometer is a device which measures electric current. A needle is held in place by a spring or coil, … WebThe most accurate method of measuring an electric current is by using a device called a galvanometer. A galvanometer consists of a rectangular conducting coil which is free to pivot vertically in an approximately uniform horizontal magnetic field --see Fig. 31. The magnetic field is usually generated by a permanent magnet.

We want to use the galvanometer to measure the voltage of DC power supply 10V. But, Can we use it? We need to know the full scale voltage of the galvanometer before. From …
WebThe galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current. Principle: The potentiometer is based on the premise that … Webgalvanometer. The ratio ‘ ’ is called current reduction factor. The equation (13) shows that if know the ballistic constant ‘K’ and the maximum throw in the galvanometer ‘θ0’ or we have the knowledge of current reduction factor we can find the total charge passing through the galvanometer in a short interval of time. This time must be
Webparallel with the galvanometer by closing switch S. Adjust the value of Rs such that the deflection of the galvanometer is between 20 and 30 divisions. Now change the resistance of resistor R (which is connected in series with the galvanometer) such that the deflection of the galvanometer becomes maximum again. Record
