Answer:

The main function of resistors in a circuit is to control the flow of current to other components. Take an LED (light) for example. If too much current flows through an LED it is destroyed. So a resistor is used to limit the current.

Answer:

A resistor is a small component that’s designed to provide a specific amount of resistance in an electronic circuit.

Resistors are used for many reasons in electronic circuits. The three most popular are

Limiting current: By introducing resistance into a circuit, resistors can limit the amount of current that flows through the circuit. In accordance with Ohm’s law, if the voltage in a circuit remains the same, the current will decrease if you increase the resistance.

Dividing voltage: You can also use resistors to reduce voltage to a level that’s appropriate for specific parts of your circuit. For example, suppose your circuit is powered by a 3 V battery but a part of your circuit needs 1.5 V. You could use two resistors of equal value to split this voltage in half, yielding 1.5 V.

Resistor/capacitor networks: Resistors can be used in combination with capacitors for a variety of interesting purposes.
