How to Measure Voltage in a Circuit — Multimeter Basics for Beginners

Welcome back to the multimeter beginner series!
In today’s video, we build a simple circuit using a 9V battery, breadboard power supply, a green LED, and RGB LEDs — then learn how to measure voltage properly using a multimeter.

You’ll learn:

• Why voltage is always measured across a component
• How to measure the voltage of a 9V battery
• How to check the voltage at each branch of a circuit
• How to measure voltage across resistors and LEDs
• Why all the voltage drops add up to around 3.3V on each branch
• How to avoid the most common beginner mistakes
This is the perfect starting point if you’re new to electronics, breadboards, or multimeters.

👉 Next video in the series: How to measure current using a multimeter (and why current is measured through the circuit)

If you’re learning electronics from scratch, this series will make everything finally click.
