Network Analysis

    Network analysis is the branch of electrical engineering that deals with the circuits (containing electrical components) and analysis (solving) of those circuits using different methods and laws.

 Ohm's Law:
    So long as the physical state of the conductor remains the same the potential difference applied between the two ends of the conductor bears a constant ratio to the elastic current passing through it.

V ∝ I
V = IR 
Where , V - Potential Difference 
   I - Current 
          R - Resistance 

  Limitations of Ohm’s law:

  • Material of the conductor should be the same.
  • The cross sectional area/dimension of conductor should be the same.
  • The temperature of the conductor should be the same.
  • The characteristics of V-I are nonlinear after a certain value of voltage.

 Basic Electrical Components:

  1. Resister 
  2. Inductor 
  3. Capacitor 
  4. Voltage and current source

 Basic Laws:-

  1. Kirchhoff’s Current Law (KCL)
  2. Kirchhoff's Voltage Law (KVL)

    Resistor is an electrical component which limits and regulates the flow of electric current in an electrical circuit.

            where , V- Voltage applied

 I- Current flowing through resistor
                 R- Resistance of resistor
