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). WebbWith the equivalent resistance RA of the ammeter consisting of the galvanometer and the shunt in parallel, we have 50 mV= IgRg = IshRsh = IRA. Hence Rsh = 50/98 = 0.5102 Ω and RA = 50/100 = 0.5 Ω. Example 7.18. Accuracy of an ammeter. Let us use the ammeter of Example 7.17 to measure the current through a resistance R = 20 Ω.
