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. WebbThe main purpose of a current shunt in calibration is to measure a high current range. If you are looking for a cheaper with higher accuracy standard (above 4:1), compared to a clamp meter, then this is a good choice. Common accuracy specifications of current shunts are ±0.1%, ±0.25% or ±0.5%.
