  1. In the resistance colour code, the fourth band signifies
    1. tolerance level
    2. power of ten
    3. the total value of resistance
    4. the material of the resistor
Correct Option: A

The first and second band represent the numerical value of the resistor, and the colour of the third band specify the power-of-ten multiplier. Reading the resistor from left to right, the fourth band represents the tolerance.
