Measurement Devices

Ammeter

• An Ammeter is used to measure the current passing through a circuit.
• It should always be connected in series with the component where the current is being measured.
• The SI unit of measurement used by an ammeter is amps (A).

Voltmeter

• A Voltmeter is utilised to measure the potential difference, or voltage, across components.
• Voltmeters should always be connected in parallel across the components where the voltage is being measured.
• Measurements are taken in volts (V).

Ohmmeter

• An Ohmmeter is used to measure resistance in a circuit or individual components.
• To measure resistance accurately, the component needs to be disconnected from the circuit.
• Measurements by an ohmmeter are in ohms (Ω).

Multimeter

• A Multimeter is a versatile device that can measure current, voltage, and resistance.
• It can be used both in series and parallel, depending on what is being measured.
• It offers a practical solution when multiple measurements need to be taken in a circuit.

Oscilloscope

• An Oscilloscope displays a graph of an electrical signal, allowing for the measurement of properties such as amplitude, frequency, and time period.
• It is mostly used in complex and high frequency circuits.
• Oscilloscopes can help detect irregularities and troubleshoot in a circuit.

Signal Generator

• A Signal Generator is used to produce electrical signals in the form of a wave.
• These signals can be in the form of sine waves, square waves, or other complex waveforms.
• Signal generators are mainly used for testing and troubleshooting in electronics and signal processing.
