#4.3.3a
potential divider circuit with components
Learners will also be expected to know about a potentiometer as a potential divider.
#4.3.3b
potential divider circuits with variable components e.g. LDR and thermistor
#4.3.3c
(i) potential divider equations e.g.
\(V_{out} = \dfrac{R_2}{R_1 + R_2} × V_{in} \) and \(\dfrac{V_1}{V_2} = \dfrac{R_1}{R_2} \)
(ii) techniques and procedures used to investigate potential divider circuits which may include a sensor such as a thermistor or an LDR.
