DC circuit questions
Solve series, parallel and mixed networks; calculate charge, energy and power.
Electricity questions and practice
Follow current and potential difference through circuits and practical data.
Potential divider practice
Calculate outputs, choose a resistor and predict LDR, thermistor and loading effects.
Resistivity practical questions
Process wire measurements, find resistivity from a resistance–length graph and evaluate uncertainty.
Internal resistance practical questions
Use terminal voltage and current data to find emf, internal resistance and load power.
Capacitor discharge practical questions
Calculate capacitor discharge, interpret log-linear graphs and find capacitance and time constants.
Linked exam-style questions
Start with DC circuits for current, resistance and potential difference. Use the practicals when your question includes measured data.
