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 1.2 k ohms resistor is placed across an 18-V source The minimum acceptable power rating for the resistor is?
1/2 watt (In theory you could use a "0.27 Watt" resistor, however there would be no safety factory and there is no standard value resistor that size.)
What is the relationship between Wattage and resistance of resistor?
There is no direct relationship.Power ('wattage') is a measure of the rate at which the resistor can dissipate energy; excessive power means that a resistor cannot dissipate energy fast enough to prevent its temperature becoming excessive -excessive enough to damage the resistor.As the rate at which a resistor can dissipate energy is determined by its physical size, a resistor's power rating(maximum continuous power it can handle without exceeding its rated temperature) depends on the physical size of the resistor.On the other hand, the resistance of a resistor is notaffected by its physical dimensions, as a resistor can be manufactured to any particular value of resistance for whatever physical size is necessary to achieve its rated power.If you know a resistor's rated power and its resistance, then you can calculate the maximum continuous current that resistor can handle without overheating (using the equation: power = current squared x resistance).
What do you call the variable resistor when it is set up to alter the size of the voltage over the resistor?
A potentiometer.
What are the objectives about resistor color code?
The color code is a means of displaying the resistance value of the component, correct to 2 significant figures, on an area where printed digits would be unreadable because of its small size.
How do you prevent shock by capacitors?
Discharge the capacitor, normally with a resistor accross the terminals (Calculated size)
Why resistor size does not varies with its value?
A: A resistor size is determined by the usage or its power dissipation. the bigger the size the more power it can dissipate due to the extra surface. SIZE is a function of power dissipation and has nothing to do with its value
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
Is their any relation between foot size and penis size?
depends how big your foot is ;)
Is your penis bigger if you werent cicumsized?
There is no relation between size and foreskin

Can you measure the physical size of a resistor to determine its wattage?
there might be ways to get the power rating by measuring the size of the resistor. but as the physical size of the resistor increases, its power rating also increases..
Relation between nominal pipe size and millimeter?
There is no relationship. NPS is based on inches.
What is the relation between human body length and the human eye's iris size?
no relationship
What is the relationship between sample and population?
From a sample of a population, the properties of the population can be inferred.
What is relation between nanotechnology and attoms?
Nanotech is so tiny that it is around the size of a few atoms
What do you call the variable resistor when it is set up to alter the size of the voltage over the resistor?
A potentiometer.
