Question

What is the purpose of a resistor in a circuit?

Answer 1

The purpose of a resistor in a circuit is to limit the flow of current. This can be useful for protecting components from overloading and for adjusting the voltage level. By controlling the amount of current flowing through a circuit, resistors can also help to modulate or filter electrical signals.

Answer 2

The purpose of a resistor in a circuit is to limit the flow of current and reduce the voltage level. Resistors are used to adjust signal levels, set biasing conditions, and control current flow in transistors and LEDs. They are also used in voltage dividers, filters, and feedback circuits.
