Superposition Theorem
Superposition Theorem
In a linear circuit, the voltage or current response of an element due to multiple independent sources is equal to the sum of the responses due to each source acting alone.
Linear Circuit
Linear Circuit
A circuit whose output is directly proportional to its input.
Superposition Limitation for Power

Study Notes
Superposition Theorem
- The voltage/current across an element in a linear circuit is the sum of the voltages/currents due to each independent source acting alone.
- A linear circuit has an output that is linearly related to its input.
- Superposition is based on linearity, thus not applicable to power calculations.
- To apply superposition:
- Turn off all independent sources except one.
- Calculate the contribution of the active source.
- Repeat for each independent source.
- Sum the contributions algebraically.
- Dependent sources are left intact.
Source Transformation
- Transforming a voltage source in series with a resistor to a current source in parallel with the resistor (and vice versa).
- Formula for source transformation: Vs = Is * R, Is = Vs / R.
- Applies to dependent sources if handled carefully.
Thevenin's Theorem
- A linear two-terminal circuit can be replaced by an equivalent circuit with a voltage source (Vth) in series with a resistor (Rth).
- Vth is the open-circuit voltage across the terminals.
- Rth is the input resistance when independent sources are turned off.
Norton's Theorem
- A linear two-terminal circuit can be replaced by an equivalent circuit with a current source (In) in parallel with a resistor (Rn).
- In is the short-circuit current through the terminals.
- Rn is the input resistance with independent sources turned off.
- Rn = Rth
- In = isc
- Vth/Rth = In
