Question

Choose the correct color code for resistor 270 ohms +/- 10% with explanation .

1.Green Blue Red Gold

2.Red Green Brown Silver

3.Red Violet Brown Silver

 4.Red Violet Black Gold

​

Answer 1

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)
