Ohm's law, resistance, V-I characteristics of ohmic and non-ohmic conductors
- Resistance of a carbon resistor determined from colour codes is (22000±5\%) Ω. The colour of third band must be : Answer: 4. Orange Colour code: first two bands give the digits, the third band gives the power of ten (multiplier), the fourth gives toleran... 1
- The color code of a resistance is given below :(figure: colour bands Yellow, Violet, Brown, Gold)The values of resistance and tolerance, respectively, are : Answer: 4. 470 Ω , 5% Four-band colour code: first two bands are digits, the third is the multiplier, the fourth is tolerance. Yellow = 4, V... 1
