Calculate the currents, potential differences, and resistances in direct current series circuits using the appropriate equation.
V=I×R
Describe an experiment to investigate the resistance of a wire, including drawing the corresponding circuit diagram.
Recall that resistance remains constant for fixed resistors but changes with current for components like heating elements and lamp filaments.
Use graphs to find out if a circuit element is linear or non-linear, and link the shape of each curve to the element's function and properties.
Describe experiments to investigate the current-voltage characteristics of circuit elements such as lamps, diodes, LDRs, and thermistors, including drawing their circuit diagrams.
Represent circuits using standard conventions for positive and negative terminals and symbols for common components like filament lamps, diodes, LDRs, thermistors, switches, and fixed or variable resistors.
