What is a multimeter?
A multimeter is a tool used to measure different aspects of electrical circuits. It combines several functions in one device, making it versatile for various tasks.
Here are its key uses:
Voltage (Volts): Measures the electrical potential in a circuit.
Current (Amps): Measures the flow of electricity in a circuit.
Resistance (Ohms): Measures how much a component resists the flow of electricity.
Continuity Test: Checks if there's a complete path for electricity between two points.
Capacitance (Farads): Measures the ability of a component to store electrical charge.

Knowing how to use a multimeter is important for:
Troubleshooting: Helps find and fix issues in circuits.
Safety: Ensures safe usage and prevents accidents. Students should never measure mains.
Maintenance and Repair: Useful for keeping electronic devices in good working condition.
Quality Assurance: Ensures components meet standards during manufacturing.
In summary, a multimeter is a handy tool for measuring and understanding electricity in circuits, making it essential for both learning and practical applications.
