Resistors are measured in units of Ohms (Ω).
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.
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
Resistors have resisting power(resists the electric power).Due to having the resistive property, the name resistor is given to such electrical device.
parallel combination of resistors are used in house circuits
The different colored bands on it.
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
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
Color bands are used on resistors to indicate their resistance value and tolerance. Each color represents a digit, and by combining multiple colors, you can determine the resistance value. The bands help quickly identify the resistor's value without needing to use a multimeter or other measuring tools.
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.
The resistance in Ohm
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.
Resistors are measured in units of Ohms (Ω).
most of the resistors commonly used are carbon resistors
If you mean rubber bands for braces, I think you can get them from your orthodontist.
Fixed resistors use color bands to indicate their values because this method allows for easy identification of resistance values without taking up much space on the small components. The color coding system is standardized, enabling quick reading and reducing the risk of misinterpretation that can occur with printed numbers, especially in varying lighting conditions. Additionally, the bands are durable and resistant to wear, ensuring that the values remain visible over time.
