Describe an experiment to determine resistance using a voltmeter and an ammeter and do the appropriate calculations

Know that the p.d. across an electrical conductor increases as its resistance increases for a constant current

Draw and interpret circuit diagrams containing cells, batteries, power supplies, generators, potential dividers, switches, resistors (fixed and variable), heaters, thermistors (NTC only), light-dependent resistors (LDRs), lamps, motors, bells, ammeters, voltmeters, magnetising coils, transformers, fuses and relays and know how these components behave in the circuit
