Give applications of resistors in series
Answers
Hey mate!!!!!
Lighting in your house: the light switch is in series with any amount of parallel lamps you want to turn on and off at the same time.
When, within a circuit, you have a power indicator LED, you will put it in series with a resistor to make sure the current through the LED is correct.
Hope it helps you.

Explanation:
Laptop charger
Your laptop charger has tens (if not hundreds) of resistors for controlling current flow through different components. The figure below displays the resistors in the opened laptop charger.

Mobile phone charger
Just like the laptop, a mobile phone charger contains a number of resistors that are responsible for controlling the required amount of current. You might have noticed the amount of current on your mobile charger displaying something like 500 mA, 700 mA, 900 mA, 1.0 A or 2.0 A. This is actually the amount of current. A resistor is a basic component responsible for controlling this flow through the mobile phone.

Fan Speed Controller [Potentiometer]
All of us are familiar with the rotating knob that is used for controlling the fan speed. The rotating knob is actually a potentiometer whose rotation changes the amount of resistance.

Lightning bulb (Carbon / Metal film)
The electronics circuits in CFL, LED and other lightning lamps contain resistors. The figure below displays an opened CFL containing metal film resistor (gray).
