Calculator for Resistors

Resistor Colour Coding		Sheet resistors often have the following colour coding
1st colour ring	2nd colour ring	3rd colour ring	4th colour ring	Resistance value:
				Ohm
				Tolerance

Please note: there are also precision multipliers with 5 colour codes, whereby 4 of them indicate the value.

When two resistors R1 and R2 are in parallel, then R_ges = (R1 * R2) / (R1 + R2)

Resistors in parallel			Please enter decimal separators as "."
R1 =	Ohm	and	R2 =	Ohm	R_ges =	Ohm

When two resistors R1 and R2 are in series, then their resistance values are added up.

Resistors in series			Please enter decimal separators as "."
R1 =	Ohm	and	R2 =	Ohm	R_ges =	Ohm
