Q: What does IP Physics Notes (Upper Secondary, Year 3-4): 12) Direct Current Circuits cover?
A: Combine series/parallel rules, potential dividers, and sensor behaviour to solve IP DC circuit problems.
Quick recap -- DC circuit analysis hinges on current and voltage sharing rules. Once you master how resistances combine and how potential dividers behave, thermistor/LDR sensor circuits become straightforward.
