Are two (or N) resistors in series more precise than one big resistor?

Let's say I have one 2 kΩ resistor with 5% tolerance. If I replace it with two 1 kΩ resistors with 5% tolerance, will resulting tolerance go up, down, or remain unchanged? I'm bad with ...

4/5 band resistor - extra black band

I have two resistors which need to be replaced. I tried to determine the value, but it can't make sense of these black bands: For reference the bands are: brown - silver - green - brown - black ...

Can a 10% resistor be used as a 1% resistor?

If my schematic calls for a 1% resistor, can I use a 10% resistor that measures to the correct resistance within 1% or is there some quality to tolerance beyond what it measures Ohm-wise? For example,...

Reducing the tolerance of resistors manually

All the resistors available come with a finite amount tolerance. This is undesirable particularly in highly sensitive systems. While we can use resistors with the least tolerance available, I want to ...

Why are we still using resistors with %5 tolerance while they can even manufacture a 14.318182MHz crystal?

Year is 2012 and I can only find %5-tol resistors in the local market. They can make transistors at molecular scale, they can manufacture 14.318182MHz crystals, they can place trillions of flip-flops ...

Resistors - binning and weird distributions

I read about a little quirk related to binning resistors in a comment on this recent question. Some manufacturers will sell, for example, 1% and 5% resistors that are really made in the same batch. ...

How to calculate aging tolerance of Resistor?

I wanted to calculate the worst case minimum and maximum value of Resistor 1K by considering all the tolerances(initial tolerance,temperature,environmental factors and aging). Here is the link for ...

Replace Tight Capacitors for Better Tolerance?

There are some capacitors (10 \micro F and 4.7 \micro F) which are limiting my development of Raspberry Pi Hats because they are provided only with tolerance of 10% or greater. It seems that the ...
