Ammeters are connected in series with whatever device’s current is to be measured. A series connection is used because objects in series have the same current passing through them. (See Figure 3, where the ammeter is represented by the symbol A.)...
Calibrating AC voltmeters and ammeters for different full-scale ranges of operation is much the same as with DC instruments: series “multiplier” resistors are used to give voltmeter movements higher range, and parallel “shunt” resistors are used to allow ammeter movements to measure currents be...

Likewise, the null detector simply indicates when the voltage between points 1 and 2 are equal, which (according to Kirchhoff’s Voltage Law) will be when the adjustable voltage source (the battery symbol with a diagonal arrow going through it) is precisely equal in voltage to the drop across...
Draw a circuit, with two resistors, Y; a) Place an ammeter on one resistor, and a voltmeter on the other. b) Why must both be placed that way? How can a galvanometer be converted into a ammeter and voltmeter? Explain? State the principle of a potentiometer and expla...
