IP Physics Notes (Upper Secondary, Year 3-4): 12) Direct Current Circuits

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.

Keep your practice loop tight via our IP Physics tuition hub-it links each topic here to quizzes, diagnostics, and WA-style problem sets.

Series vs Parallel Essentials

• Series
  • Current is identical everywhere in the loop.
  • Potential differences add: $V = V_1 + V_2 + \cdots$
