How Do You Determine The Resistance Value Of A Resistor?
Resistors are by far the most common components in most electronic circuits. However, since they are produced very inexpensively and often have round bodies, their resistance value cannot be printed on them. For that reason, the most common type of resistors (carbon film resistors) use a common color coding scheme to allow you to quickly determine their resistance value. Determine the type of resistor. Though most resistors will be carbon film resistors, there are several other types of resistors used in many circuits. For example, wire wound resistors are used in high-voltage power supply circuits and won’t follow this color coding scheme. Surface mount carbon film resistors don’t follow the color coding scheme either, but have their resistance value printed on them. Find the orientation of the resistor. A resistor is not a polarized component, it doesn’t matter which way you insert it into the circuit. It does, however, matter which way you read the color bands. Look for a gold or si
