Permanent and Induced Magnetism

Master the fundamental concepts of electric charge, current flow, and potential difference in simple direct-current circuits.

Investigate electrical resistance, apply Ohm's law, and analyse the current-voltage graphs of linear and non-linear components.

Analyse current, potential difference, and total resistance in series and parallel circuits using rules and quantitative calculations.

Understand how thermistors and LDRs function and how they are integrated into potential divider sensing circuits.

Master the principles of UK mains supply, alternating current, three-pin plug wiring, and electrical safety mechanisms.

Calculate electrical power and energy dissipation in domestic appliances and examine energy transfers to motors and heaters.

Explain the architecture of the National Grid and why high-voltage power transmission enhances efficiency.

Explore magnetic poles, field patterns, magnetic materials, and Earth's magnetic core.

Examine how electric currents produce magnetic fields, build solenoids, and apply the motor effect.

Master multi-equation problem solving combining charge, current, voltage, resistance, power, energy, and time.

Master experimental apparatus, data recording, zero error handling, and required practical methods for GCSE electricity.

Interpret, compare, and calculate properties from current-voltage graphs and sensor calibration curves.

Calculate the magnetic force on a conductor and determine the direction of force using Fleming's left-hand rule.

Explain how the motor effect produces continuous rotation in DC electric motors and drives sound devices.
