What are photo resistors?
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device

Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.

Can variable resistors store electrical charge?
NO. Variable capacitory can store a small charge

What might variable resistors be used for in a cinema?
Variable resistors in a cinema may be used to adjust the volume of the speakers, control the intensity of lighting in different areas, or regulate the speed of the projector fan.
What are the resistors on a blower motor?
Resistors on a blower motor are components used to control the speed of the motor by adjusting the voltage supplied to it. They function by dissipating excess voltage as heat, allowing for variable speed settings in heating, ventilation, and air conditioning (HVAC) systems. Typically found in the blower motor circuit, these resistors can be in the form of fixed resistors or resistor packs, depending on the design of the system. Proper functioning of these resistors is crucial for efficient blower operation and overall system performance.
What components are placed in an electrical circuit to control the amount of resistance in circuit?
resistors, variable potentiometers
Do potentiometers have polarity?
no there is no consideration of positive or negative legs in case of resistor.
What is the advantages of variable resistor?
When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider. Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.

Difference between variable and fixed resistor?
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
What are the 3 kinds of variable resistors?
