In an electrical circuit, what does a resistor do?

  1. Increases current flow

  2. Decreases voltage

  3. Stores electrical energy

  4. Limits current flow

The correct answer is: Limits current flow

A resistor is a component used in electrical circuits to limit the flow of current. It does this by creating resistance, which reduces the amount of current flowing through the circuit. A resistor does not increase current flow (choice A) or store electrical energy (choice C). While it ultimately may result in a decrease in voltage (choice B), this is not the primary function of a resistor. Therefore, the incorrect options can be ruled out and the correct answer is D.
