the power is more evenly distributed in a carbon rod than a wire
hi resistance wire wound can have 100s of feet of very fine wire
very prone to heat failure
solid carbon distributes the heat over the entire volume of the carbon
carbon resistors are far better with higher voltages and resistances

How will amps and current differ in a series if you get resistors with different resistance?
-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes. -- The current is always the same at every point in a series circuit, no matter how many resistors of the same or different values are in the circuit.
What is the difference between a series ohmmeter and a shunt ohmmeter?
Basically, your series and shunt ohmmeters differ in circuit configuration. Your series ohmmeter is configured in a way that your "meter" (which has internal resistance) is connected in series to your "measured resistor" and we all know that those TWO resistances will ADD up causing some sort of inaccuracy. While on the other hand, your shunt ohmmeter is configured in a way wherein your "meter" is connected in PARALLEL to your "measured resistor" that will ease-up the inaccuracy but will only measure resistances ranging from 200 Ohms to 400 Ohms (typically and depending on your configuration).
Why the color coded value of a resistor is differ from the value read from the tester?
The color bands show the nominal resistance. The actual resistance is within some percentage (tolerance) of the nominal resistance, so the measured resistance is close to the nominal but not exactly the same. Also resistance varies with factors like temperature and age of the device.
What is the Difference between carbon steel and hi speed steel?
carbon steels are steels which contain upto 2% carbon and some other trace elements such as silicon, manganese etc., Tool steels have greater amount of alloying than the alloy steels of iron. alloying elemnts include chromium, tungsten, molybdenum, carbon, vanadium, nitrogen in the form of nitrides, manganese, silicon, cobalt. These two mainly differ in the pattern in which they are manufactured. tool steels are manufactured from electric furnace techniques where as most carbon steels are manufactured from conventional melting processes. This is done to exhibit good alloy characteristics and impart greater refined structure which cannot be obtained from the conventional say a cuppola furnace or a bessemer furnace.

What would be the best size for resister?
Electronic resistors differ from equipment to equipment. Without prior knowledge of the equipment you intend to use resistor for, it can't be answered.
How does molecule of carbon monoxide differ from a molecule of carbon dioxide?
Carbon monoxide is CO and carbon dioxide is CO2.
How does a carbon sink differ from carbon sequestering?
By sinking down all the way
How do the atoms of carbon 12 and carbon 14 differ?
The isotope carbon-12 has 6 neutrons; the isotope carbon-14 has 8 neutrons.
How does protein differ from other energy nutrients?
carbon
How will you differ a resistor and resistance?
resistance is the hindrance caused to some flow be it flow of liquids,flow of positive charges etc. whereas resistor is the device used to vary the resistance of the electric circuit

What aspect of a series circuit is the same for each resistor as well as the total circuit?
Current is the same..... In a series circuit: V=V1+V2+...+Vn and R=R1+R2+...*Rn If voltage remains constant at the source (total circuit), and resistors differ in resistance (R1,R2,...,Rn), and V=I*R, then: I*R=I1*R1+I2*R2+...+In*Rn Seeing as I*R=const and voltage drop across every resistor is proportional to its resistance: I*R=I*(R1+R2+...+Rn) Therefore: I=I1=I2=...=In
When considering carbon-12 carbon-13 and carbon-14 what is it that makes all of these carbon?
They all have the same number of Protons-6. They differ in the number of neutrons present.
How do different isotopes of an element differ?
Two isotopes differ in the number of neutrons in the nucleus. For example, Carbon-14 has 8 neutrons differing from Carbon-12 which has 6 neutrons.
Individual steroids differ in the what attached to the carbon rings?
In the "side chains"
How does the molecular structure of graphene differ from the other allotropes of carbon diamond and graphite?
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
