Resistance Part One: Base Electronics: 5

This lesson covers electrical resistance, explaining it as the opposition to current flow in a circuit, measured in Ohms. It discusses the extremes of resistance, from infinite to none, using a switch as an example. Resistors are introduced as components to control current and voltage. A water flow analogy is used to illustrate how resistors impede current, similar to hair clogging a pipe. The lesson explains how to adjust current and voltage by changing resistance, ensuring optimal flow in circuits. It concludes with a review of key concepts, setting the stage for further lessons on circuit analysis.

Describe a scenario where increasing voltage is necessary due to higher resistance.

Why might one want to limit current flow in a circuit?

What happens to current flow when resistance is introduced into a circuit?
