Which component is used to increase resistance in an electronic circuit?

The component used to increase resistance in an electronic circuit is the resistor. Resistors are specifically designed to restrict the flow of electric current, which in turn increases resistance in a circuit. They come in various values measured in ohms, allowing designers to control the current flow according to the needs of the circuit. By increasing resistance, resistors can also help manage voltage levels and protect sensitive components from excessive current, ensuring the circuit operates safely and effectively.

Other components, such as transistors, capacitors, and diodes, serve different functions within a circuit. Transistors are used for amplification and switching, capacitors store and release electrical energy, while diodes allow current to flow in only one direction. Thus, they do not function to increase resistance in the way that resistors do.
