Study Notes
Circuit Analysis Theorems
- Thevenin's theorem is used for the analysis of a transistor circuit.
Circuit Fundamentals
- A mesh is the most elementary form of a loop that cannot be further divided into other loops.
Circuit Elements
- An active element supplies electric energy to the circuit.
- A source element is an element that supplies electric energy to the circuit.
Energy and Units
- Joules are used to express the amount of electric energy stored in an electrostatic field.
Ideal Voltage Source
- The internal conductance of an ideal voltage source is zero.
- An ideal voltage source has zero internal resistance.
Capacitors and Inductors
- Capacitors oppose changes in voltage.
- Inductors oppose changes in current.
Circuit Configurations
- In a parallel circuit, the voltage across each element is the same.
- In a parallel circuit, the equivalent resistance is less than any one of the resistors.
- In a parallel circuit, the current through any one element is less than the source current.
