What is mangnitude?
Magnitude refers to the size or scale of something. In various contexts, it can indicate the physical size, strength, intensity, or importance of a particular object or event.
Which is A change in size shape or state of matter?
a change in size, shape or the state of matter is a physical change. True for A+.
How can changes in the size of a glacier indicate climate changes?
no
How do you differ in size?
I am a virtual assistant and do not have a physical size as humans and objects do.
What'a physical properties detected by sight?
Physical properties detected by sight include color, shape, size, and texture. These visual characteristics allow us to distinguish objects, assess their materials, and understand their spatial relationships. For example, the color can indicate the type of material, while shape and size can provide information about functionality and scale. Additionally, texture can be inferred by observing light reflections and surface patterns.
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..
What physical characteristic determines the power rating of a resistor?
The size of a resistor is a physical characteristic that determines its power rating.
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 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.
What is the approximate increase in size from a one watt to a 2 W carbon resistor?
The increase in size from a 1 watt to a 2 watt carbon resistor typically involves a larger physical dimension, primarily due to the need for better heat dissipation. While the exact increase can vary by manufacturer, it is common for a 2 W resistor to be about 1.5 to 2 times larger in length and diameter compared to a 1 W resistor. This ensures the resistor can handle the increased power without overheating.

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 is the reason for putting a voltage rating on resistors?
Due to the physical construction and size of the resistor, at a certain voltage, the insulation will break down and the applied voltage will arc over. This is generally bad. Operating the resistor within its voltage rating will prevent this failure mode.
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
What is meant by resistor package?
A resistor package refers to the physical encapsulation format of a resistor, which determines its size, shape, and mounting style. Common types of resistor packages include through-hole (such as axial or radial leads) and surface-mount (like 0201, 0402, etc.). The package type impacts how the resistor is integrated into electronic circuits and affects thermal management and space efficiency. Selecting the appropriate resistor package is essential for ensuring compatibility with a circuit board design and overall performance.
How many watt values are there for resisters?
Some of the more common values are 1/8, 1/4, 1/2, 1 and 2 watts. On PC boards the larger resisters are not placed adjacent to the board but connected into the board above the board using standoffs. This is to let air circulate around the resistor to carry away the heat generated by the resistor. The physical size of the resistor reflects the resistors ability to dissipate the heat which builds up inside the resistor. As the wattage goes up so does the physical size of the resistor. Resistors that dissipate very large amounts of power (watts) are usually wire-wound resistors. Wire-wound resistors can be as high as 100 watts.
How does the Resistance and Wattage relate to maximum voltage of a wirewound resistor?
The power rating of a resistor is determined by its physical size. The greater its surface area, the better it can dissipate energy, so the higher its power rating. Knowing its power rating and its resistance will determine the maximum voltage that can be applied to it in order to ensure the resulting current doesn't cause the resistor to overheat. This can be determined by manipulating the equation, P = U2/R.
