Answer:
The value of resistance of a resistor having four colour bands in the order yellow, violet , orange and silver is 47000 ± 10%
Answer:
Explanation:
yellow = 4
violet = 7
orange = 3 zeros
silver = 10% tolerance.
So the value of the resistor is
47000 +/-10%
10% means 4700 ohms either side of 47000 so that means
42300 < x < 51700
Usually a ten % tolerance is more than adequate for most applications.
