What is the primary function of a resistor in an electronic circuit?

• A. To amplify signals
• B. To regulate current flow
• C. To store energy
• D. To control voltage levels

Answer: (B)

The primary function of a resistor in an electronic circuit is to regulate current flow. Resistors provide resistance to the flow of electrical current, which helps control the amount of current that can pass through a circuit. This is crucial for protecting components from excessive current that could lead to damage. By adjusting the resistance, a resistor can influence the voltage across other components in the circuit, ensuring they operate within their specified limits. While other components may have overlapping functions, such as capacitors storing energy or transistors amplifying signals, the fundamental role of a resistor is to manage current flow effectively. This regulation maintains stability and functionality in electronic devices, making resistors essential for virtually all circuits.
