The commercial carbon resistor has four colour rings such as yellow, green, orange and silver rings as shown. The resistance 'R' of the carbon resistor is given by:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $\left(45 \times 10^3 \pm 10 \%\right) \Omega$
The total resistance = $(45×10^3±10\%)$
Yellow (First Band) = 4
Green (Second Band) = 5
Orange (Third Band) = Multiplier of $10^3$
Silver (Fourth Band) = Tolerance of ±10%
