The Design And Construction Of 2kva Inverter

CHAPTER THREE
3.0     CONSTRUCTION AND METHODOLOGY
3.1     COMPONENTS AND FUNCTION: There are some component used to built-up an inverter and their main function of operation, by the way of the arrangement on vero board.
3.1.1 RESISTOR
A resistor is passive two terminal of an electrical components that implement opposition to the flow of electric current as circuit element0. The unit of measuring how much the resistor will oppose current is in ohms (Ω), to determine the outcome of the resistor is by using ohm’s law.
Ohm’s law state that the current flow through a conductor between two points is directly proportional to the difference across the two points.
There are two main types of resistors which are fixed and variable resistors.
FIXED RESISTOR     
This type of resistor has a resistance that only changes slightly with the temperature, times or operating voltage.

VARIABLE RESISTOR                                                              
The variable resistor is very important component that is commonly used in electrical & electronics device to perform things, such has tone, volume and voltage devider.
i.    Wire wound
ii.    Carbon
iii.    Conductive plastic
A resistance value can be through their colour code identification of their outer body colour.

3.1.2 CAPACITOR   
This is also known as electrolyte condenser, is a simple passive device that is used to stored electric charges. The capacitor is a component which has the ability or capacity to stored energy in the form of an electrical charging producing a potential difference (static voltage) across its plate. There are many different types of capacitor available from very small capacitor used in resonance circuit to larger capacitor but they all store energy: examples are: ceramic capacitor, tantalum electrolytic capacitor, electrolytic capacitor etc,
The capacitor used for these project are electrolytic and ceramic capacitor for smoothing or filtering of the current perfectly.
