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:
Resister
Inductor
Capacitor
Voltage and current source
Basic Laws:
Kirchhoff’s Current Law (KCL)
Kirchhoff's Voltage Law (KVL)
Resister -
Resistor is an electrical component which limits and regulates the flow of electric current in an electrical circuit.
V=IR
where , V- Voltage applied
I- Current flowing through resistor
R- Resistance of resistor
