Question

The colours on the resistor shown here are red, orange, green and gold as read from left to right. How much is the resistance according to colour code?

Answer 1

Answer:

Black 0 0 1 Silver +/-10%; Gold +/-5%

Brown 1 1 10 Silver +/-10%; Gold +/-5%

Red 2 2 100 Silver +/-10%; Gold +/-5%

Orange 3 3 1,000 Silver +/-10%; Gold +/-5%

Yellow 4 4 10,000 Silver +/-10%; Gold +/-5%

Green 5 5 100,000 Silver +/-10%; Gold +/-5%

Blue 6 6 1,000,000 Silver +/-10%; Gold +/-5%

Violet 7 7 10,000,000 Silver +/-10%; Gold +/-5%

Gray 8 8 100,000,000 Silver +/-10%; Gold +/-5%

White 9 9 1,000,000,000 Silver +/-10%; Gold +/-5%

Explanation:

This resistor, read from left to right, has the colored bands of RED, VIOLET, YELLOW, SILVER.

Using the formula and chart above, the resistance would be:

R = 1st Digit x 10 + 2nd Digit) x Multiplier

R = (RED X 10 + VIOLET) x YELLOW

R = (2 x 10 + 7) x 10,000

R = 27 x 10,000

R = 270,000 ohm (270 K ohms)

Since the final band is silver, the tolerance is 10%.

l hope this is help you
