What does a resistor measures?
Resistors are measured in units of Ohms (Ω).
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
What are Resistors wired in series?
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
Why are resistors called resistors?
Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.
What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
How do you tell the difference between fixed resistors?
The different colored bands on it.
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
What does the third and of a resistor mean?
That depends on the resistor, the resistors that are color coded come with either 4, 5 or 6 bands. On resistors with 4 bands, the 3'rd band is the multiplier. F.ex if we have a Resistor colored brown:red:orange it would mean 1 : 2 : 3 which translates to (10+2)*10^3, or 12*1000 = 12k Ohm On resistors with 5 or 6 bands, the 3'rd band is just another digit For examle a 5-band resistor starting with brown|red|orange|yellow would mean 1 | 2 | 3 | 4 which translates to (100+20+3) * 10^4 or 123*10000 = 1,23M Ohm
Why are there couler bands on a resistor?
i presume you meant colour, but there are colours on resistors so we know what the resistance is.
Why do resistors not have numbers printed on them?
Because they're very small components. It's easier to mark them with coloured bands, then you can 'decode' the bands according to the internationally agreed colour-coding system.
What does the R mean in resistors?
The resistance in Ohm
What do the coloured bands of the resistors mean?
They are a standard code with each individual colour representing a single whole number (1-10) indicating the resistance or ohm value. Additionally the gold band represents 5% "tolerance" and the resistance value is more precise. The silver banded resistors have only 10% tolerance & therefore are not as precise in ohm value. Such should be cheaper to buy than the gold ones.
What does a resistor measures?
Resistors are measured in units of Ohms (Ω).
What are those materials of resistors?
most of the resistors commonly used are carbon resistors
Where do you purchase teeth effect bands?
If you mean rubber bands for braces, I think you can get them from your orthodontist.
What is carbon composition resistors?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
