What IS a capacitor? :
What IS a capacitor? A capacitor is a component that stores electrical charges.
They are used to smooth out the electrical current
They can also be used to make a time delay.
What DOES a capacitor look like? :
What DOES a capacitor look like?
What DOES Polarised mean? :
What DOES Polarised mean? Polarised is a term used when a component has a positive and a negative pole.
It describes the orientation of the electric field.
What ARE Capacitors Measured in? :
What ARE Capacitors Measured in? Capacitors are measured in ‘Farad’ (F)
The capacitance of 1F when 1v across the legs produces a current of: 1A.
A ‘Farad’ is too much of a large capacitance so capacitors are usually measured in ;
What DOES Charging mean? :
What DOES Charging mean? When a capacitor is being charged; the power supply pulls electrons from one plate and pushes electrons to the other.
This charge of a capacitor builds up until you reach a point when the power supply had insufficient energy.
HOW to calculate capacitors? :
HOW to calculate capacitors? Series: You can calculate the total capacitance of two or more capacitors in a series circuit. Use this Formula.
Slide 9:
In Parallel: To calculate the total number of capacitance in a parallel circuit, you basically just add all the capacitors capacitance together.
