Question


k) what is the current through the galvanometer when the reading on A2 (lab-made) is 100.0 mA? Table 3 Current readings from both the lab-made ammeter and the DMM. 20.0 mA 40.0 mA 60.0 mA 80.0 mA 100.0 mA A2 (ab-made, use a shunt wire of length 5 (cm) A1 (DMM) A2 (lab-made, use a 20.0 mA 40.0 mA 60.0 mA 80.0 mA. 100.0 mA shunt wire of length (cm) A2 (lab-made, use a 20.0 mA 40.0 mA 60.0 mA 80.0 mA 100.0 mA shunt wire of length E-5 12 (cm) A1 (DMM) In Table 3, which set of data from the lab-made ammeter is the best match with the data from the DMM? Why? (k) what is the current through the galvanometer when the reading on A2 made) is 100.0 mA?

Explanation / Answer

2nd set of readings are the best match as the error percentage is less.

%error =(measured value -true value)/true value *100

current through galvanometer=113.83mA
