The resistor is arguably the most common component. Its primary function is to oppose the flow of electric current, a property known as resistance (measured in Ohms, Ω). By limiting current, resistors protect sensitive components like LEDs. They also divide voltages to create specific reference levels. In a schematic, a resistor is represented by a zigzag line (US) or a rectangle (IEC). The colorful bands painted on a resistor’s body are a code that tells you its resistance value and tolerance.
An inductor is essentially a coil of wire that stores energy in a magnetic field when current flows through it. A series of looped coils. introduction to basic electronic components ppt
They can be anything from a simple timer (like the famous 555 Timer) to a complex microprocessor. The resistor is arguably the most common component
