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.
Laptop charger
Your laptop charger has tens (if not hundreds) of resistors for controlling current flow through different components.
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, such as metal film resistor HPMRY series from Microhm Electronics.
Street lighting (LDR)
Automatic street lighting system uses LDR (light dependent resistors) in their working. A photoresistor is variable resistance device whose resistance changes with the light intensity falling upon it. During daylight, the resistance of lamps is adjusted to turns off the lights. When the sun falls the resistance also changes, this variation in resistance is used to turn on the lights.
MICROHM Electronics provides a large amount of resistors with different types nof only for consumer electronics, but also for automotive, industry, telecommunication, new energy and more.
