A circuit with ideal elements is shown. Which one of the following options correctly identifies all the linear elements in the circuit?
To determine which elements in the circuit are linear, let's first understand the characteristics of linear and non-linear elements:
- Linear Elements: These elements follow the superposition principle. The relationship between voltage and current is linear, which means their parameters (resistance, inductance, capacitance) do not change with voltage or current.
- Non-linear Elements: These elements do not follow the superposition principle. Their parameters change with voltage or current.
In the given circuit, we have the following elements:
- R (Resistor): Linear element. The voltage across a resistor is directly proportional to the current through it (Ohm's Law: V = IR).
- L (Inductor): Linear element. The voltage across an inductor is proportional to the rate of change of current through it (V = L \frac{di}{dt}).
- C (Capacitor): Linear element. The current through a capacitor is proportional to the rate of change of voltage across it (I = C \frac{dv}{dt}).
- D (Diode): Non-linear element. A diode conducts current in one direction only; its voltage-current relationship is not linear.
From the above analysis, we see that R, L, and C are linear elements, while D is a non-linear element.
Conclusion: The correct answer is R, L, and C only, as they are the linear elements in the circuit.
