Khan Academy
Khan Academy: Resistance: Pencil Resistor
A pencil causes a change in the deflection, similar to the effect of adding an electromagnet. Why? Watch this video as a pencil is used in a circuit as a resistor! [1:03]

Khan Academy: Ac Analysis Intro 2
Here's a preview of how AC analysis is going to work. To get ready we need to review some of the ideas from trig and complex numbers. [8:57]

See a worked example of question 2ab: 2015 AP Physics 1 free response.
Khan Academy
Khan Academy: Variable Resistor (Pencil)
We use the inside of a pencil (graphite) to apply different 'lengths of pencil' to the circuit. What relationship do you observe between the length of graphite and deflection angle? Watch this video to find out! [1:27]

Khan Academy: Listen to Variable Resistance
Here we draw a line on a page and use it as a variable resistor in series with a speaker. What relationship do we hear? Does it sound linear? Watch and find out![1:11]
Khan Academy
Khan Academy: Series Load
Why does the deflection change when an electromagnet is attached to the circuit? Does it matter what side of the electromagnet we test? Watch this video to find out. [1:11]
