Describe the functional differences between series and parallel circuits, specifically how current and potential difference are affected by changing a component's resistance.
Describe practical investigations into the brightness of bulbs in series and parallel circuits, drawing the associated circuit diagrams.
Explain qualitatively why adding resistors in series increases the net resistance, while adding resistors in parallel decreases the net resistance.
Solve complex problems for circuits containing resistors in series by using the concept of equivalent resistance.
Explain the design and use of direct current series circuits for measurement and testing purposes.
Analyze the effects of changing current in filament lamps, diodes, thermistors, and LDRs.
Evaluate the effect of changing light intensity on an LDR.
Evaluate the effect of changing temperature on a negative temperature coefficient thermistor.
