Sketch and explain the current-voltage graphs for a resistor of constant resistance, a filament lamp and a diode

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

Explain the use and operation of trip switches and fuses and choose appropriate fuse ratings and trip switch settings
