200 KΩ + 10 % -

The Gold or Silver band is always placed to the right. The resistor value is read from the left to right. If there is no tolerance band, then find the side that has a band closest to a lead and make that the first band.

Equation 2 0 x 10,000 1,000 = 1K Resistor = 200 K with a + 10 % Tolerance = 200,000
