Carbon Composition Resistor Schematic Symbol. Math r math is the resistance. For example 8k2 as part marking code in a circuit diagram or in a bill of materials bom indicates a.
Now does this resistor have a particular symbol to represent it schematically you may wonder. The physical size and material used for resistance is rated in watts. The chemical makeup that causes resistance is accurately controlled in the resistor manufacturing process.
For example 8k2 as part marking code in a circuit diagram or in a bill of materials bom indicates a.
Resistor values can be purchased in a range of values from less than 1 ohm to over 22 mega ohms. Math r math is the resistance. Math l math is the length of the object. Such carbon composition resistors usually have a brown cylindrical body with a wire lead on each end and colored bands that indicate the value of the resistor.
