A resistor is a passive electrical component with the primary function to limit the flow of electric current. The international IEC symbol is a rectangular shape with leads at each end as shown in the figure at left. In the USA, the ANSI standard is very common and represents a fixed resis...
The resistance value is specified in ohms, the standard symbol is “R” orΩ. Resistor values are often stated as “k” (kilo, or times 1,000) or “M“, (meg, or times 1,000,000) for convenience. There are a few conventions that are followed, and these can cause problems for t...

The curved plate represents the cathode (negative) of the capacitor, and the other plate is anode (positive). Sometimes a plus sign is also added to the positive side.The SI unit of capacitance is farad (Symbol: F). The unit is named after Michael Faraday, the Great English Physicist....
Each symbol represents a packaged component with two or more pins or leads to connect it to other parts of the circuit. Symbols have unique representations across different PCB design software to avoid confusion between similar looking parts. ...
A symbol representing such a quantity. For example, in the expression a2 + b2 = c2, a,b, and c are variables. Variable Able to vary or be varied. Variable winds or seasons; a variable quantity; a variable resistor Variable Likely to vary. Variable Marked by diversity or difference. Vari...
A quantity capable of assuming any of a set of values. Parameter A factor that determines a range of variations; a boundary An experimental school that keeps expanding the parameters of its curriculum. Variable A symbol representing such a quantity. For example, in the expression a2 + b2 = ...

LDR (Light Dependent Resistor) is a type of resistor that works on photoconductivity i.e. resistance changes according to the light intensity
The Unicode character U+2393 “⎓” represents DC voltage. Sometimes, a straight line is also used as a symbol. In a circuit diagram, there are several DC sources available to get DC voltage. Abatteryis the most commonly used source for a DC voltage. The below figure shows the symbol ...
