A carbon resistor has three olurs blue, yellow and red respectively. What will be the resistance?

Text Solution

Verified by Experts

Sequence of colour code of carbon resistor is :
Yellow, blue, red
Yellow colour corresponds to 4
Blue colour corresponds to 6
Red colour corresponds to `10^2`
Fourth band is absent
`:.` Tolerance is 20%
So `R = (46 xx10^(2) pm20%)Omega`
