Question

If the colour code for a resistance is
Green Red Orange Golden Resistance

What is the resistance and tolerance value of resistance.

Answer 1

The resistance can be calculated as per the color code of the respective bands.

Green – $5$

Red – $2$

Orange – $3$

The first two bands give us the significant numbers and the third band gives us the decimal multiplier

Therefore,

Resistance $R=52\times {10}^3\Omega \pm 5$%

Where, $5$% is the tolerance of gold.
