Here are the color codes for values in ohms of resistance
The value of resistance (Rp) from a parallel connection of two resistors R1 and R2 can be calculated using the following formula:
RP = R1 * R2 / R1 + R2
can see a resistance of colored rings. Each color corresponds to a figure (see table below right). The correspondence between numbers and colors of the rings is what is called the color code and to determine the value Ohms of resistance . To read this value, we must first place the resistance in the right direction. In general, resistance has a gold or silver ring, it takes place right . In other cases, the large ring that must be put right. There are three types of resistance : those 4 rings, 5 rings and 6 rings. For resistors 5 and 6 rings, the first three rings give the significant figures , the fourth gives the multiplier (power of 10 with which we must multiply the numbers significant). For resistors with 4 rings, the rings are the first two significant digits and the third is the multiplier
Color Code
| Color | Value |
| money | -2 |
| gold | -1 |
| black | 0 |
| brown | 1 |
| red | 2 |
| orange | 3 |
| yellow | 4 |
| green | 5 |
| blue | 6 |
| purple | 7 |
| gray | 8 |
| white | 9 |
If resistance is 5 rings, is the sixth that was removed from the diagram above.
If the resistance has 4 rings, what are the Grades 3 and 6 who were removed from the diagram above
A mnemonic trick to remember the order of colors from black (0) to white
(9) is remember the phrase: Do I Eat Or Nothing You Burn Your
