The Thevenin and Norton theorems are helpful tools in understanding electric circuits. They depend on a few important ideas:
Linear Circuit Parts: The theorems assume that all parts of the circuit, like resistors, capacitors, and inductors, work in a straightforward way. This means we can use simple equations to show how voltage and current are related.
Passive Parts: Only parts that do not add energy to the circuit are considered. This means we leave out devices like transistors and operational amplifiers, which can add energy.
Time Consistency: The theorems assume that the circuit's features stay the same over time. This helps us analyze the circuit in a stable way.
Two-Terminal Networks: These theorems only work for circuits that have two connection points, making it easier to study how they take in and give out energy.
Superposition: The theorems use the idea of superposition. This means that when there are several sources of electricity in a circuit, we look at one source at a time to understand the overall effect.
While these ideas are useful, they can limit how we use these theorems in real-world circuits. Circuits that have non-straightforward parts or change over time might need different methods to analyze them.
