Dc Ammeter Resistance at Carol Ernest blog

Dc Ammeter Resistance. Describe how a galvanometer can be used as either a voltmeter or an ammeter. If the ammeter resistance is not. If we place a resistor in parallel with the permanent magnet moving coil (pmmc) galvanometer, then the entire combination acts as dc ammeter. Normally, the ammeter’s resistance is very small compared with the resistances of the devices in the circuit, and so the extra resistance is negligible. Draw a diagram showing an ammeter correctly connected in a circuit. Find the resistance that must be placed in. (see figure 7(a).) however, if very small load. A voltmeter is placed in parallel with the voltage source to receive full voltage and must have a large resistance to limit its effect on the circuit. Find the resistance that must be placed in series with a galvanometer to allow it to be used as a voltmeter with a given reading. It is important for an ammeter to have low resistance because it is always connected in series with the load to have its current measured. Our simple dc ammeter can be further extended by having a number of shunt resistances, with each resistor sized for a particular current range.

How do you increase the range of an ammeter?
