Resistor
resistor symbol
Resistor component gives resistance that is barrier to the current flow in a circuit. There are two different symbols are widely used in schematics that is Zigzag format (US style) and Rectangle shape, this will have two pins and three pins if variable resistor. Unit of resistor is Ohm Ω.
Capacitor
