📖 Key Concepts

Series: Same current flows through all components; total resistance = sum of individual resistances; voltage divides proportionally.
Parallel: Same voltage across all branches; total conductance = sum of conductances; current divides inversely proportional to resistance.
Voltage Divider: Output voltage is a fraction of input voltage, determined by the resistor ratio: V_out = V_in × R₂/(R₁+R₂).
Use Ohm's Law (V = IR) and power (P = VI) to understand circuit behaviour.
