A photoresistor (or light-dependent resistor) is an element whose resistance changes with the amount of light shining on it. When exposed to light, the resistance of a photoresistor decreases, and when in darkness, the resistance increases. This property makes photoresistors useful in light-sensing applications.

What material stops the flow of electrical current?

Materials that are considered insulators, such as rubber, plastic, and glass, can stop or greatly reduce the flow of electrical current. These materials have high resistance to the flow of electricity, preventing electrons from moving freely through them.


Two factors that greatly affect air resistance on falling objects are the size and what?

Two factors that greatly affect air resistance on falling objects are the size and shape of the object. Smaller objects and objects with a more streamlined shape experience less air resistance compared to larger or less aerodynamic objects.


Why wheatstone bridge is unsuitable for measurement of law resistance?

The Wheatstone bridge is unsuitable for measuring low resistance because it relies on comparing the unknown resistance with other resistors in the bridge circuit, which limits its sensitivity for low resistance values. The voltage drop across the low resistance would be too small to provide accurate readings due to the small voltage differences involved. Additionally, any small variations in the resistors can greatly affect the accuracy of the measurement for low resistances.


Why was electricity important to discover?
