1. Resistors:

What is Resistor? Resistors are passive components that oppose the flow of electric current and control the amount of resistance in a circuit. Resistors dissipate energy in the form of heat when current passes through them.

Resistor unit - ohms (Ω)

1.1 Properties and Functions of Resistors:

  • Control the flow of current and voltage levels in a circuit.
  • Determine the current distribution and voltage division in a circuit.
  • Can be fixed or variable, allowing for precise control of resistance.
  • Used in voltage dividers, current limiters, and biasing circuits.

1.2 Use of Resistor:

  • Setting the gain or amplification factor in amplifiers.
  • Controlling the brightness of LEDs.
  • Biasing transistors for proper operation.
  • Providing protection against excessive current flow.

2. Capacitors:

What is Capacitors? Capacitor store and release electrical energy, acting as temporary reservoirs of charge. They consist of two conductive plates separated by an insulating material (dielectric).

Capacitors are characterized by their capacitance value, measured in farads (F).

2.1 Properties and Functions of Capacitors:

  • Store electrical energy in an electric field.
  • React to changes in voltage, resisting rapid voltage fluctuations.
  • Pass alternating current while blocking direct current.
  • Used for energy storage, filtering, and timing in circuits.

2.2 Use of Capacitors:

  • Storing energy in power supplies and electronic systems.
  • Smoothing voltage fluctuations in power lines.
  • Timing and frequency generation in oscillators.
  • Filtering noise and ripple in signal process.

3. Inductor:

Inductor

What is Inductor? Inductor is a wire wrapped around the substance in the coaxial/solenoidal form.

The amount of inductance in an inductor is measured in henry (H).

3.1 Properties and Functions of Inductors:

  • Resist changes in current flow.
  • Store and release energy in magnetic fields.
  • Block high-frequency signals while allowing low-frequency signals.
  • Used in filters, oscillators, and energy storage circuits.

3.2 Use of Inductors:

  • Filtering noise in power supplies and audio systems.
  • Storing energy in switching power supplies.
  • Generating magnetic fields in motors and transformers.
  • Tuning radio frequencies in antennas and RF circuits.

4. Electrical Diodes:

What is Diode? Electrical Diodes are semiconductor devices that allow current to flow in only one direction. They consist of a PN junction, created by combining P-type and N-type semiconductor materials.

4.1 Properties and Functions of Diodes:

  • Enable the flow of current in one direction (forward-biased) while blocking it in the opposite direction (reverse-biased).
  • Convert AC to DC in rectifier circuits.
  • Regulate voltage levels and protect components.

4.2 Use of Diode:

  • Rectifying AC power into DC in power supplies.
  • Protecting sensitive electronic components from reverse voltage.
  • Generating and detecting radio waves in communication systems.
  • Controlling current flow in switching circuits.
