Wed Aug 15, 2018 2:30 pm
Electronics is a branch of an engineering, which deals with electronic and electrical circuits like Integrated circuits. The electronic circuit is defined as, it is a combination of various electronic components that allows the flow of electric current. The electronic components consist of two or more terminals, that are used to connect one component to another component to design a circuit diagram. The electronic components are soldered on circuit boards to make a system.
The electronic circuit symbols mainly involve wires, power supplies, resistors, capacitors, diodes, transistors, meters, switches, sensors, logic gates, audio devices and other components.
Wires
A wire is a two terminal, single and flexible material, that allows the flow of power through it. These are mainly used to connect the power supplies to PCB( Printed Circuit Board) and in between the components. The different types of wires will be as
Wires: A single wire with two terminals will pass the current from one component to another.
Wires Jointed: When two or more wires are connected with each other that is called as wires jointed. The jointing or shorted of wires at one point is indicates the “blob”.
Wires not Jointed: In complex circuit diagrams, some wires may not connect with others, in this case bridging is commonly utilized.
Power Supplies
A Power supply/ power supply unit is an electronic device, that supplies electric energy to an electrical load. The flow of an electric current will be measured in terms of Watts. The function of power supply is, it converts energy from one form to another according to our requirement. The various types of power supplies are

In order for a circuit to be properly called electronic, it must contain at least one active device. Components incapable of controlling current by means of another electrical signal are called passive devices. Resistors, capacitors, inductors, transformers, and even diodes are all considered passive devices.

It does not have the same symbol. variable resistor has a rectangle shape figure while variable capacitor has a two vertical parallel lines though they both have an arrow pointed and place in the same direction because that indicates the variable.puralan jomark wrote:why the variable reistor and variable capacitor have the same symbols

Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes. Passive components can't introduce net energy into the circuit. Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers.zekmayor09 wrote:They have 2 types of electronic components which are the Active and Passive Electronic Components.

Rheostat is an adjustable or variable resistor. It is used to control the electrical resistance of a circuit without interrupting the flow of current .A preset resistor is a smaller PCB mounted version of a potentiometer. These are useful where adjustment or configuration of a circuit needs to be made but such adjustment only occurs during building a circuit, not during normal usemargs wrote:Rheostat and preset symbol is both variable resistor and has a quite similar symbol. can you differentiate the two?
