ELECTRONIC PRACTICE - Practice Mode

Explanation:

<p><span style="font-size:16px">Light dependent resistors, LDRs or photoresistors are often used in electronic circuit designs where it is necessary to detect the presence or the level of light.</span></p> <p><span style="font-size:16px">These electronic components can be described by a variety of names from light dependent resistor, LDR, photoresistor, or even photo cell, photocell or photoconductor.</span></p>
