Basic Electronic Circuits

Components and Principles

  • Resistance, Potentiometer, Transistor: These are fundamental electronic components.
  • AC Cycle: It completes a cycle reaching 220V at 50 cycles per second (50 Hz).
  • Potentiometer Function:
    • Left (Counter-Clockwise): Lowest resistance, LED is brighter.
    • Right (Clockwise): Highest resistance, LED is dimmer.
  • Diode Behavior (L1, L2, and L4):
    • L1 and L2 light up because they are correctly polarized (positive to positive and negative to negative), allowing current

1. Ohm’s and Kirchhoff’s Laws

Ohm’s Law: Defines the relationship between voltage (V), current (I), and resistance (R) in a circuit. It is expressed as:

V = IR

  • Theoretical Explanation: It shows that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
  • Graphical Representation: A plot of current (I) versus voltage (V) for a resistor is a straight line, indicating a linear relationship.

Kirchhoff’s Laws:

  • Kirchhoff’s Current
