Web24 de nov. de 2024 · A galvanometer measures the magnitude and the direction of electrical current in a circuit. These measurement devices operate using a moving coil method. This method is based on the work of... WebIn an electric circuit, even if the switch or loop is closed, it is difficult to know whether the current is flowing, hence for this purpose galvanometer was...
Web31 de dez. de 2013 · As the galvanometer's resistance (100 Ohms) is much much greater than the shunt resistance (10 mOhm), we can pretty much disregard the effect of paralleling the galvanometer's coil to our shunt. Thus, in effect the Ammeter we have created, has 10 milliOhms of resistance, which is pretty much negligible, and reads up to 1 Ampere current.
