Describe the use of ammeters (analogue and digital) with different ranges

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

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