Which components are found in a resistor-capacitor (RC) circuit?

In a resistor-capacitor (RC) circuit, the essential components are resistors and capacitors. Resistors are used to limit the current and control the voltage within the circuit, while capacitors store electrical energy temporarily and release it when needed. This combination allows for various applications, such as filtering, timing, and signal processing.

The interaction between the resistor and capacitor defines the circuit’s behavior, particularly in how it responds to changes in voltage over time. The resistor slows the charging and discharging of the capacitor, creating specific time constants that dictate how quickly the circuit responds to input signals. This characteristic is fundamental to the function of RC circuits in applications like audio systems and data processing.

The other options refer to components not typically paired in an RC circuit. Inductors are associated with inductor-capacitor (LC) circuits, transformers involve electromagnetic induction rather than direct resistive or capacitive elements, and transistors and diodes belong to different classes of circuits that involve switching and rectification, respectively.
