Photoresistors

Light-sensitive resistor or Photoresistors are electronic components that resistance will decline if there are additional light intensity about it. Photoresistors can also refer to a light-dependent resistor (LDR), or a photoconductor. Photoresistors...

Capacitor

Capacitor is a device that can store energy in the electric field, by collecting an internal imbalance of electric charge. Capacitor has units called farads. Discovered by Michael Faraday (1791-1867). Capacitors are now also known as the...

Kinds of Resistors

Fixed Resistor Carbon film resistor is one of the most common types of resistors used and has very good frequency response. Carbon Film Resistor material is a mixture of carbon with a long piece of ceramic rods. This resistor value itself is...

Thermistor

Thermistor is a resistor that is usually used to measure temperature. Thermiastor will work if exposed to temperatures or temperature, whereby when the temperature of the thermistor changes in thermistor resistance will also vary. Thermistor...
