Introduction to Electronics & Ohm’s Law
Lesson 1 · Beginner · 25 min · card-by-card
Electronics with Haktan
Engineering Workbench · Module 01
This lesson runs card by card instead of as one long page. Read one idea, then prove it with one question. A question card locks the flow until it is solved — a correct answer opens the next step.
What you will learn4 blocks
- ▸The difference between electricity and electronics
- ▸What an electronic circuit really is
- ▸Voltage (V), current (I) and resistance (R)
- ▸The resistor: physics, symbol, values and unit conversions
- ▸Ohm’s Law — solved for all three unknowns
- ▸A battery + resistor + LED series circuit
How the flow worksstep player
- ▸One concept or one question per card
- ▸The progress bar and step counter show your position
- ▸Question cards unlock only when answered correctly
- ▸“Show solution” is available after one attempt — you are never stuck
- ▸Use ← / → on the keyboard, or the Back / Continue buttons
