Final answer:
Explanation of ohmmeters, ammeters, and digital multimeters for measuring current, voltage, and resistance in electrical circuits.
Explanation:
Ohmmeter is an instrument that applies a voltage to a resistance, measures the current, calculates the resistance using Ohm's law, and provides a readout of this calculated resistance. It works based on the relationship between current, voltage, and resistance within an electrical circuit.
Ammeters measure the electric current in a circuit, while ohmmeters measure the resistance of a component by applying a known voltage and measuring the resulting current, enabling calculation of resistance using Ohm's law.
A digital multimeter combines the functions of ammeters, voltmeters, and ohmmeters in a single handheld device, providing a versatile tool for measuring voltage, current, resistance, and more.
