Question

What color code corresponds to a resistance of 234x105±10% with a temperature coefficient of resistance equal to 25x10-6/Co?

Answer 1

For a 6-band type carbon composition resistor;

1^st band - 1^st significant figure, 2

2^nd band - 2^nd significant figure, 3

3^rd band - 3^rd significant figure, 4

4^th band - multiplier, 10⁵

5^th band - tolerance , $^+_-$ $10\%$

6^th band - temperature coefficient in parts per million per $°c$

$(ppm/°c)=25ppm/°c$

Therefore the color code for: $234×10^5 {^+_-}10\%$ temp coefficient $25×10^{-6}/°c$ is;

Red, Orange, Yellow, Green, Silver, Yellow
