To determine the resistance of a carbon resistor based on the color bands, we need to refer to the standard resistor color code. The colors represent digits and multipliers as follows:



  • Green: 5

  • Red: 2

  • Orange: Multiplier of 10^3 (1,000)



Given the color bands: Green, Red, Orange


The resistance value is calculated as follows:



  1. First digit: Green = 5

  2. Second digit: Red = 2

  3. Multiplier: Orange = 10^3 (1,000)



So the resistance is:


Resistance=(52)×10^3 ohms=52,000 ohms=52 kilo-ohms


Answer: The approximate resistance of the resistor is 52 kΩ.

The colour code of green =5,red=2,orange is 10^-3 ohms.
The Two colour band indicate the significant no and the third colours band indicate decimal multiplier .
Thus we get 52 ×10^-3 ohm.

Read the following text and answer the following questions on the basis of the same:Types of resistors Most common type of resistor is Carbon Composition Resistors. Carbon resistors are a cheap, general purpose resistor used in electrical and electronic circuits. Their resistive element is manufactured from a mixture of finely ground carbon dust or graphite and a non-conducting ceramic powder to bind it all together. The ratio of carbon dust to ceramic (conductor to insulator) determines the resistive value of the resistor. Higher the ratio of carbon, lower the overall resistance. Film Type Resistors consist of Metal Film, Carbon Film and Metal Oxide Film .Such resistors are generally made by depositing pure metals, such as nickel, or an oxide film, such as tin-oxide, on an insulating ceramic rod or substrate. The resistive value of the resistor is controlled by increasing the desired thickness of the deposited film giving them the names of either “thick-film resistors” or “thin-film resistors”. Film type resistors can achieve much higher ohmic value compared to other types. Another type of resistor, called a Wirewound Resistor, is made by winding a thin metal alloy wire (Nichrom e) or similar wire on an insulating ceramic former in the form of a spiral helix. These types of resistors are generally only available in very low ohmic value with high precision . They are able to handle much higher electrical currents than other resistors of the same ohmic value with much excessive power ratings. These high power resistors are moulded into an aluminium heat sink body with fins attached to increase their overall surface area to promote heat loss and cooling.In carbon composition resistors, ______ the ratio of carbon, _____ the overall resistance.
