Revise this section after electric fields
Carry out calculations using this equation.
Explain the effect of varying 2 of the variables on the 3rd.
Recognise the circuit symbols for polarised and non-polarised capacitors.
Explain the practical differences between the two and suggest possible practical applications for each.
Practical: You have been shown electrolytic and non-electrolytic capacitors of widely varying capacitances (we have some very large caps. retrieved from an old amplifier!)
See animation on a variable capacitor's design. See the animation on charging a capacitor.
