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. :-p

"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.
 

FAQ: Color band colors for 1kΩ resistor

What do the color bands on a 1kΩ resistor represent?

The color bands on a 1kΩ resistor represent the resistor's resistance value, tolerance, and sometimes its temperature coefficient.

How many color bands are typically found on a 1kΩ resistor?

There are typically four color bands on a 1kΩ resistor. However, resistors with five or six bands may also exist for more precise measurements.

What is the color code for a 1kΩ resistor?

The color code for a 1kΩ resistor is brown, black, red, and gold. Brown represents the number 1, black represents the number 0, red represents the multiplier 10^2, and gold represents the tolerance of ±5%.

How do I read the color bands on a 1kΩ resistor?

The color bands on a 1kΩ resistor are read from left to right. The first two bands represent the first and second digits of the resistance value, the third band represents the multiplier, and the fourth band represents the tolerance.

Why do resistors have different color band combinations?

Resistors have different color band combinations to indicate different resistance values, tolerances, and temperature coefficients. This allows for easy identification and sorting of different resistors.
