The number of electrons is dependent of the photons frequency. How does the LDR (photoresistor) works The resistance is very high in darkness, almost high as 1MΩ but when there is light that falls on ...

Most of the PC desk lamps available in the market light up whenever there is an input power. These don’t take into account whether there is a real need for the light or not. Here is an intelligent PC ...

Photoresistors, also commonly referred to as light-dependent resistors (LDRs), are a class of variables resistors which change their resistance depending on how much light is hitting the resistor.

In a potential divider, you have two resistors connected in series. One of these resistors can be a variable resistor, like an LDR (light dependent resistor) or a thermistor ...

Save guides, add subjects and pick up where you left off with your BBC account. The resistors in a potential divider can have fixed values, or one may be a variable component like an LDR (light ...
