Color band colors for 1kΩ resistor

[pyroknife]

Homework Statement

What are the color band colors and associated band values for a 1kΩ resistor

The Attempt at a Solution

resistor color codes are read like so:
ab*10^c±tol
1kΩ=10*10^2
a=1, b=0, 10=c

Now I get confused. What should the tol be?

And just in case you have other questions about the color codes:

Hey! Is this some kind of joke?

A 0Ω resistor, marked with a single black band.​

hmmmm... Sure would make the homework helper's jobs a lot easier. :tongue2:

"I have a circuit with 6 resistors in parallel and 3 resistors in series, all are zero ohms. How do I find the equivalent resistance?"

tol = Tolerance. The problem did not ask for the tolerance, so you can ignore that for this problem.

The tolerance (tol) for a 1kΩ resistor is typically indicated by a fourth band, which can be either gold or silver. Gold represents a tolerance of ±5%, while silver represents a tolerance of ±10%. Therefore, the complete color band sequence for a 1kΩ resistor would be: brown-black-red-gold (±5%) or brown-black-red-silver (±10%). This means that the actual resistance of the resistor can vary by either 5% or 10% from the stated value of 1kΩ.
