Resistors limit the flow of electrical current in a circuit.
dimmer swithces for lights usually contain variable resistors
photo resistors, or light dependent resistors, are devices with variable resistance, that cahnges depending on how much light is hitting the device
mmg
Both resistors will have the voltage of the battery.
As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.
dimmer swithces for lights usually contain variable resistors
Resistors are either fixed value, or variable. A variable resistor has three terminals; one at either end and one attached to a moving 'wiper', and can be connected either as a potentiometer or as a rheostat. So 'potentiometers' and a 'rheostats' are different applications for variable resistors. A potentiometer uses all three terminals, and is used to control levels of potential; whereas a rheostat uses just two of the three terminals, and is used to control current.
toaster have variable resistot
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.

NO. Variable capacitory can store a small charge
dimmers in cinemas or rooms

allmost every electronic devices uses resistors..(it is needed in all circuits)
Both resistors will have the voltage of the battery.
It represents that two resistors are connected in parallel.
