Series vs Parallel rules — "SVSS / PVSS":
Series: Same current, Voltages sum, Sum of resistances.
Parallel: Same voltage, Currents sum, Smaller total resistance.
Christmas lights trick:
Old fairy lights = series (one breaks, all go dark). Modern house lights = parallel (one breaks, rest stay on). Match the circuit type to this real-world example to remember which rule applies.
Parallel resistance check — "Always Less":
Parallel total resistance is ALWAYS less than the smallest resistor in the group. If your answer is bigger — it's wrong. No exceptions.
