Study Notes
Kirchhoff's Current Law (KCL)
- Defines the algebraic sum of currents entering a closed curve or surface as zero at any given time.
- Holds for closed curves or surfaces.
- A loop or closed path begins and ends on the same node without touching any other node more than once.
Kirchhoff's Voltage Law (KVL)
- Defines the algebraic sum of the voltage drops around any closed path as zero at any given time.
Circuit Analysis Methods
- Mesh or Loop Analysis: Application of KVL, introduced by Maxwell in 1881, for analyzing circuits.
- Nodal Analysis: Application of KCL, developed in 1901 and refined in 1960, for analyzing circuits.
Loop Analysis: Applying KVL within a Circuit
- Uses a combination of KVL and Ohm's Law to calculate the voltage drop across each resistor.
- Requires defining a current for each loop, and then applying KVL to each loop.
Nodal Analysis: Applying KCL within a Circuit
- Calculates all node voltages in a circuit.
- Involves applying KCL at each node, treating the reference node as ground.
Systems and Linearity
- Systems are characterized by their input-output relationships.
- Linearity in circuits refers to a direct relationship between output voltages or currents and input sources.
- Outputs of a linear circuit are a linear combination of independent source values.
Superposition Theorem
- Applicable to linear circuits with multiple independent sources.
- States that any output (voltage or current) can be calculated by summing the contributions of each independent source acting alone, while the other sources are deactivated.
- Utilizes the additivity and homogeneity properties of linear networks.
Maximum Power Transfer Theorem
- Determines the load resistance that results in maximum power transfer to a load network.
- The maximum power transfer occurs when the load resistance (RL) equals the Thevenin equivalent resistance (Rth).
Thevenin's
- Represents an arbitrary two-terminal linear network as an equivalent circuit with a voltage source (Voc) in series with a resistance (Rth).
- The open circuit voltage (Voc) is the voltage across the two terminals when no external load is connected.
- The Thevenin resistance (Rth) is the equivalent resistance of the network when all independent sources are deactivated.
Norton's Theorem
- Represents an arbitrary two-terminal linear network as an equivalent circuit with a current source (Isc) in parallel with a resistance (Rth).
- The short-circuit current (Isc) is the current that flows when the two terminals are shorted.
- The Thevenin resistance (Rth) is the equivalent resistance of the network when all independent sources are deactivated.
