Discover How Electric Circuits Work: Current, Voltage, and Resistance

You will explore the key components of electric circuits and learn how current, voltage, and resistance work together using Ohm's Law.

What You'll Learn

You learn that circuits need a closed path for current flow.

You discover voltage pushes current while resistance opposes it.

You apply Ohm's Law to calculate current, voltage, and resistance.

You identify conductors, insulators, and key circuit components clearly.

What You'll Practice

You will identify roles of voltage, current, and resistance in circuits.

You will apply Ohm's Law to solve circuit calculation practice problems.

You will distinguish circuit components like ammeters, switches, and resistors.

Why This Matters

Understanding how current, voltage, and resistance work together gives you the foundation to explain, build, and stay safe around the electrical systems that power everything in your world.
