What is another name for a light dependent resistor?

• A. Photoresistor
• B. Thermistor
• C. Diode
• D. Capacitor

Answer: (A)

Light levels control the resistance of this component: brighter light lowers its resistance, while darkness raises it. Because the device changes its resistance in response to light, the standard name is photoresistor. It’s sometimes called a photoconductive cell as well. This distinguishes it from a thermistor (which changes with temperature), a diode (a PN-junction device), and a capacitor (which stores charge).
