Sparky the Lightbulb - Mascot Test
This page shows all Sparky mascot images and admonition styles for reference. Check that all images have a transparent background and do not have excessive padding around the drawing.
Note that the images below have a dashed blue border so you can clearly see the padding.

Sparky's Welcome
Welcome to the Circuits course! I'm Sparky, your guide through the fascinating
world of electronic circuits. Buckle up — we're about to discover how electrons
flow, how components behave, and how to build real-world circuits!
Sparky Thinking
See that voltage drop across the resistor? Ohm's Law isn't just a formula —
it's describing something real happening to those electrons right now.
Sparky's Tip
When analyzing a circuit, always start by identifying the ground reference.
Everything else is measured relative to that point. Pick it wisely and the
math gets a lot cleaner.
Sparky's Warning
Don't confuse voltage and current! Voltage is the pressure pushing
electrons through a wire. Current is the flow of those electrons.
You need both to understand power — and to avoid frying your components!
Sparky's Encouragement
Circuit analysis can feel overwhelming at first — so many symbols, so many
equations. Don't worry! Every expert engineer started exactly where you are.
Keep working through the examples, one node and one loop at a time, and it
will start to click.
Sparky Celebrates
You did it! You just solved your first circuit using Kirchhoff's Laws.
That's a huge milestone — the same techniques you used here scale up to
analyze everything from smartphone chargers to spacecraft power systems.
Take a moment to appreciate what you just learned!
