Linear Circuit:
In a linear circuit, the relationship between the current and voltage is directly proportional. This means that if the current increases, the voltage will also increase proportionally. This relationship is represented by a straight line on a graph.
Examples:
A light bulb connected to a battery.
A fan connected to a power outlet.
Non-Linear Circuit:
In a non-linear circuit, the relationship between the current and voltage is not directly proportional. This means that the voltage may increase or decrease at different rates depending on the current. Non-linear circuits can exhibit different behavior depending on the current value.
Examples:
A heating element in a circuit.
A voltage regulator.
A solar panel.
Key Differences:
| Feature | Linear Circuit | Non-Linear Circuit |
|---|---|---|
| Relationship between current and voltage | Directly proportional | Not directly proportional |
| Voltage vs. current behavior | Linear | Can be non-linear |
| Typical example | Light bulb, fan | Heating element, voltage regulator |
