Everyone who has completed all steps in the program will get a badge.


An essential foundational course for study of electric circuits at any level. Learn how to state, explain, investigate and perform calculations about: - the effect of adding resistors in series on LED/bulb brightness and current strength - the effect of position on current strength in a series circuit - direct and inverse proportion - the relationships between current strength, potential difference and resistance - voltage (potential) changes across a series circuit - potential differences across resistors in a series circuit. Apply your learning to explain how three code-senders work and design a fourth that works in reverse. Also perform calculations about these code-senders. This program focusses on developing both conceptual understanding and calculation skill for series electric circuits.
