Factors affecting capacitance:
The factors which affect the capacitance of a parallel-plate capacitor are:
We may summarise this in equation form as:
C = εA/d
The units of 'C' are Farads if the units of the other quantities are:
In the case of multi-plate capacitors, capacitance is calculated using the formula: C = [(n-1)εA]/d
Where n is the number of plates and A is the area of a single plate.
