Consider a simple circuit of a battery, light bulb and pushbutton switch...
Circuit diagram. |
As long as you connect the components as shown, the lamp lights up when you push the switch...
At this point it is important to understand that you can draw a circuit diagram in many different ways. Consider the two circuit diagrams shown...
Circuit diagram of a transistor circuit I. |
Circuit diagram of a transistor circuit II. |
If you follow the lines, you realize that the two diagrams represent the same transistor circuit.
There is no standard that dictates how you have to draw a circuit diagram. However, to keep circuit diagrams clearly arranged and easy to understand, some conventions have established, also known as "Best Practice"...
