Understanding Current, Voltage, and Resistance & Basic Calculations

Lesson Overview: Electricity 101 — Voltage, Current & Resistance

Before diving into fuzz circuits, you need a solid grip on the electrical fundamentals that power them. This lesson breaks down the three essential players in any circuit: voltage, current, and resistance.

You’ll learn:

• What each of these terms actually means (no memorizing, just real understanding).
• How they interact in a circuit—using simple, relatable examples.
• How to apply Ohm’s Law to calculate values that will come up again and again in your builds.

Even if you’ve never touched electronics theory before, this lesson sets the foundation in a practical, beginner-friendly way—without drifting into academic overkill.

By the end, you’ll be able to follow voltage through a circuit, predict current flow, and size resistors with confidence.
