VDR means Voltage Dependent Resistor, which is also called varistor.
Varistor is a resistance device with non-linear volt-ampere characteristics. It is mainly used to clamp voltage when the circuit is subjected to overvoltage and absorb excess current to protect sensitive devices. Because it has the advantages of high surge withstand, large current processing and high volume absorption, fast response time and low leakage current, it is widely used in power systems, surge suppressors, motor protection, automotive electronic systems, household appliances, etc.

Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
Define zero ohm resistor.?
A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.
2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?
No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.

What are the kind of resistor?
There are various forms of resistors used for electronic circuits. You can divide it in mainly two basic types:Fixed Resistors: The resistors that come with two wires are listed in this resistor type. These kinds of resistors do not allow you to change the resistance.Variable Resistors: These types of resistors allow you to change the resistance using the resistance using the knob.Some other types or resistors are as following:Carbon Film ResistorMetal Oxide Film ResistorPrecision Metal Film ResistorWire Wound Resistor (WWR)Power Film ResistorPrecision Wire Wound ResistorHigh Power Wire Wound ResistorPhotocellLight Dependant Resistor (LDR)Voltage Dependant Resistor (VDR)

Is Light dependent resistor an example of resistor?
yes, a variable resistor
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Describe the purpose of the coloured bands on a resistor?
The purpose of colored bands on a resistor is to tell whoever is installing the resistor the amount of resistance that particuliar resistor has.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
