Measuring voltage, current, and resistance is pretty simple, especially if you have the right tools. Here’s how to do it based on what I've learned:

Tools You Need:

1. Multimeter: This is your go-to tool for everything.
2. Voltmeter: This tool is for checking voltage only.
3. Ammeter: Use this for measuring current.
4. Ohmmeter: This one is just for measuring resistance.

How to Measure:

• Voltage ($V$): Set the multimeter to measure voltage. Then, connect the two wires (called probes) to the parts you want to check.

• Current ($I$): Change the multimeter setting to measure current. You’ll need to connect it directly in line with the circuit.

• Resistance ($R$): Set the multimeter to measure resistance. Connect the probes to the resistor you want to test.

It’s really about connecting the probes correctly and reading the numbers on the screen!
