WebNov 9, 2024 · In an ammeter 10% of main current is passing through the galvanometer. If the resistance of the galvanometer is G, then the shunt resistance, in ohms asked Mar 21, … WebTheory The purpose of this lab is to be able to demonstrate Kirchhoff’s first and second rules for electrical circuits. Kirchhoff’s Rules are used instead of Ohm’s Law when the Ohm’s laws start having limitations due to circuits being more complicated. Kirchhoff’s first rule states that the sum of all currents entering a junction must equal the sum of all currents leaving …
WebNov 5, 2024 · Suppose you want 10 V to produce a full-scale deflection of a voltmeter containing a 25-Ω galvanometer with a 50-μA sensitivity. Then 10 V applied to the meter must produce a current of 50 μA. The total resistance must be: (20.4.1) R t o t = R + r = V I = 10 V 50 μ A = 200 k Ω. WebFigure 5. A small shunt resistance R placed in parallel with a galvanometer G produces an ammeter, the full-scale deflection of which depends on the choice of R.The larger the current to be measured, the smaller R must be. Most of the current (I) flowing through the meter is shunted through R to protect the galvanometer.(Note that r represents the internal …
