Series and Parallel Circuits and Resistance — Interactive Lesson (Ages 14–16)

Why do the other lights stay on when one bulb blows? Master the rules of series and parallel circuits. This 22-slide interactive lesson on electrical resistance takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Series and Parallel Circuits and Resistance in GCSE Physics

Pupils calculate charge with Q = I × t and use V = I × R, then apply the rules for current, potential difference and resistance in series and parallel circuits. They interpret I–V characteristics for an ohmic resistor, a filament lamp and a diode, describe how LDRs and thermistors respond to light and temperature, and state how ammeters and voltmeters are connected.

What Pupils Will Learn

• Calculate charge using Q = I × t.
• Use V = I × R to calculate potential difference, current and resistance.
• State the rules for current, potential difference and resistance in series and parallel circuits.
• Describe the I–V characteristics of a resistor, filament lamp and diode.
• Describe how LDRs and thermistors respond to light and temperature.
