Question

Evaluate resistance for the following color coded resistor a) Yellow Violet Black Silver b) Green Blue Red Golden

Answer 1

a) Yellow - 4 (first digit)

Violet - 7 (second digit)

Black - 0 ( i.e. 10^0 = 1)

Silver - 10% (tolerance)

Resistance = 47 * 1 + 10% ohm

Similarly

b)Green - 5

Blue - 6

Red - 2

Golden - 5%

Resistance = 56*10^2 + 5% ohm
