Yes, an RL circuit (which consists of a resistor and an inductor) is linear. This means that the relationship between the voltage and current in the circuit follows Ohm's law and the behavior of the inductor is proportional to the rate of change of current.
Since both components (the resistor and the inductor) have linear characteristics, the entire RL circuit is considered linear, meaning the voltage and current will change in a predictable and proportional manner based on the applied input, assuming ideal components and no non-linear effects.
- The resistor provides a linear relationship between the voltage and the current (V = IR).
- The inductor has a linear relationship between voltage and the rate of change of current (V = L * di/dt), where L is the inductance and di/dt represents the change in current over time.
