The order of coloured rings in a carbon resistor is red, yellow, blue and silver. What is the resistance of the carbon resistor? |
26 X 104 Ω ± 5% 36 X 104 Ω ± 5% 24 X 104 Ω ± 10% 34 X 106 Ω ± 5% |
24 X 104 Ω ± 10% |
According to colour code of carbon resistors, red stands for 2, yellow for 4, blue for 6 and silver stands for 5%. First and second band represents the first two significant figure of resistance.Third band represents the power raised to 10 in the value of resistance. Fourth band represents the tolerance. |
