Answer 2

Uses of resistor :

• Resistor usage in Circuit Functions

• Transistors and LEDs

• Resistor is used for Diving Voltage

• Resistors used for Heating

Explanation:

Resistor usage in Circuit Functions:

• There are many types of resistors which is used according to the purpose.

• In the circuit function, the variation in resistance will affect the flow of current.

• It allow the required current to flow through it by resisting the extra current.

• For example resistors used in the pitch of musical tone.

Transistors and LEDs:

• Both the devices are sensitive to electrical current. It will devastate them.

• Here the correct resistor is used in the circuit that allows the transistors and LEDs to function properly.

Resistor is used for Diving Voltage:

• The voltage divider is a kind of daisy chain which is attached to the circuit.

• If the resistor shows the correct value the voltage drop with equal range. Else its proportion determines by the resistance of each resistor and the total resistance of all the resistors in the divider.

Resistors used for Heating

• Resistors used in the heating purpose also because it convert the electrical energy into heat which makes that as a good heating element.
