Webb12 juli 2024 · You need to understand the purpose of galvanometer and of ammeter. Ammeter is connected in series with the circuit ,so full current under measurement pass through it. It is used to calculate large currents. Galvanometer is used to measure small currents and needs very small current for zero to full scale deflection (usually in mA). WebbA moving coil galvanometer has 5 0 turns and each turn has an area 2 × 1 0 − 4 m 2.The magnetic field produced by the magnet inside the galvanometer is 0. 0 2 T. The torsional constant of the suspension wire is 1 0 − 4 Nm rad − 1.When a current flows through the galvanometer, a full-scale deflection occurs if the coil rotates by 0. 2 rad. The resistance …
WebbAn ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel … WebbAmmeter: The term “ammeter” refers to an instrument or device used to measure current. The current is measured in amperes. As a result, this instrument is known as an ammeter or ampere metre and measures current flow in amperes. Although this device’s internal resistance is “0,” it still has some internal resistance.
WebbAn ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit. The "shunt" is nothing more than a resistor with a very low resistance. This shunt is connected in parallel with the ammeter - hence the name "to ...
