Lessons covering this
- Ohm's Law10 min
Solve for voltage, current, or resistance given the other two, and recognise which of the three a word problem is actually asking for.
- Power, and Why Things Get Hot9 min
Compute power from any two of voltage, current, and resistance, and use the I-squared form to predict where a station will overheat.
- Series and Parallel10 min
Tell series from parallel by what is shared, combine resistances either way, and know why capacitors break the pattern.
