Voltmeters are typically connected in parallel because they have high resistance, while ammeters are typically connected in series to measure current since they have low resistance and the voltage drop would be minimal.

How to read ammeter reading?

Ammeter resistance is typically in the range of 0.5 ohm.
However, when we connect as indicated, 10 ohm and 0.5 ohm are in parallel, resulting in a 40 amp current in the ammeter and a 2 amp current in the 10 ohm resistor.
As a result, the ammeter will read 40 amp even if only 2 amp of current is flowing through the 10 ohm resistance.
An ammeter is a device used to gauge the current flowing through a circuit. Amperes are units used to measure electric currents, therefore the name.
The ammeter is connected in series with the circuit being used to measure the current for direct measurement.
