The Circuit Builder Gizmo is easy… until the questions hit

The simulation? Easy.

Drag wires, connect stuff, bulbs light up. Cool.

Then the worksheet hits: "Explain the relationship between voltage, current, and resistance."

…and your brain just stops.

If that's you, you're not dumb — you just missed one thing.

Everything in this Gizmo is just: V = IR

Voltage = push Current = flow Resistance = blockage

That's it.

More voltage → more current More resistance → less current

Every question is just remixing this.

The part people mess up is series vs parallel.

Series: More bulbs → more resistance → dimmer

Parallel: More branches → less resistance → stays bright

Teachers don't want "what happened". They want "why it happened".

That's where most answers lose marks.

If you're even slightly unsure, don't risk it.

Way faster than redoing the whole thing after getting it wrong.
