Webgalvanometer when the galvanometer shows full-scale deflection. Then, keeping the voltage (V) of the power supply unchanged, resistance Rsh is connected in parallel with the galvanometer by closing the switch S (Fig. 3-2(b)), and, thus the galvanometer deflection becomes about one-half of its maximum value. Next, the series WebVideo Transcript. In this video, we’re going to be talking about the design of the ammeter, which is a device we use to measure current in a circuit. We’ll see how we can make an ammeter using a galvanometer and a resistor known as a shunt resistor. And we’ll see how to calculate the required resistance of the shunt resistor based on the ...

Web6 apr. 2024 · A galvanometer is one of the instruments for measuring electrical current par excellence. This device is used on electrical circuits to know and measure the intensity and direction of electrical current.. Any device can suffer irreparable damage if it experiences an electrical overload. A galvanometer can be used to prevent this from happening; they … WebThe galvanometer consist in a fine wire coil wounded on a mobile armature (the needle). It sits in a static magnetic field created by a permanent magnet. When there is a current flowing through the winding, it creates a magnetic field. The greater the current, the stronger the magnetic field created. darnay fourchambault
