An ammeter is an instrument that is used to measure the flow of electric current in a circuit. It is typically connected in series with the load in a circuit, so that the current flowing through the ammeter is the same as the current flowing through the circuit.
A voltmeter, on the other hand, is an instrument that is used to measure the voltage difference between two points in a circuit. It is typically connected in parallel with the load in a circuit, so that it does not interfere with the flow of current through the circuit.
One key difference between an ammeter and a voltmeter is the amount of current that they are designed to handle. An ammeter is typically designed to handle relatively large currents, while a voltmeter is designed to handle very small currents. This is because an ammeter must be able to measure the current flowing through the circuit without significantly affecting it, while a voltmeter must be able to measure the voltage difference without drawing too much current from the circuit.
Another key difference between an ammeter and a voltmeter is the type of movement that they use to indicate the measurement. An ammeter typically uses a moving coil movement, while a voltmeter typically uses a moving magnet movement.
