Circuits written questions
Solve H2 Physics resistor networks, internal resistance, potential dividers, capacitor combinations and RC transients, with written marking guidance.
Learning goals
- Recall circuit symbols and draw or interpret circuit diagrams.
- Draw circuit diagrams containing sources, switches, resistors, meters, lamps, thermistors, light-dependent resistors and diodes.
- Apply resistance and resistivity, interpret I–V characteristics and explain temperature effects.
- Analyse e.m.f., terminal potential difference and internal resistance in real sources.
- Analyse series, parallel and potential-divider resistor networks.
- Combine capacitors in series and parallel.
- Analyse charging and discharging in RC circuits using the time constant.
