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.

Band-1 Digit from table-1 (input1) :

Band-2 Digit from table-2 (input2) :

Band-3 No. of zeros from table-1 (input3) :


Resistance in Ohms (output1) :

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%.
