resistor calculator | resistance calculator
This page covers resistor calculator used to calculate resistance. This resistor calculator takes numeric values of four bands as inputs from user and produces resistance value as output. The rule for the resistance calculator is also mentioned.
EXAMPLE of capacitor calculator:
INPUTS: Band1= 6, Band2= 5, Band3 = 2 (i.e. 2 zeros of x100 in third
band)
OUTPUT: 6500 Ohm or 6.5K Ohms,
Check for tolerance as per Band4 and table-1 below.
For Gold, Tolerance is +/-5%.
Resistor formula used for resistor calculator
Following equation or formula is used for this resistor calculator.
| Color | Band1 | Band2 | Band3(No. of Zeros) Multiplier band |
Band4 Tolerance |
|---|---|---|---|---|
| Black | - | 0 | x1 (0) | - |
| Brown | 1 | 1 | x10 (1) | +/-1% |
| Red | 2 | 2 | x100 (2) | +/-2% |
| Orange | 3 | 3 | x1000(3) | +/-3% |
| Yellow | 4 | 4 | x10K (4) | +/-4% |
| Green | 5 | 5 | x100K (5) | +/-0.5% |
| Blue | 6 | 6 | x1M (6) | +/-0.25% |
| Violet | 7 | 7 | x10M (7) | +/-0.10% |
| Grey | 8 | 8 | x100M (8) | +/-0.05% |
| White | 9 | 9 | x1G (9) | - |
| Gold | - | - | - | +/-5% |
| Silver | - | - | - | +/-10% |
