Mid-unit check before the big test — find the gaps while there's time to fix them. A shorter assessment covering circuit fundamentals: voltage, current, resistance, Ohm's Law, and basic series/parallel concepts. Catch misconceptions before they compound. **Topics Assessed:** ✓ Voltage, Current, Resistance — definitions, symbols, units ✓ Ohm's Law — V = IR calculations ✓ Series vs Parallel Basics — current and voltage behavior ✓ Circuit Predictions — what happens when resistance changes? ✓ Practi
