Fundamentals of resistor colour code Quiz Practice…

1 k? ± 5% — Brown=1, Black=0, Red=x100, Gold=5%. Therefore 10 * 100 = 1000 ohms or 1 k?.

± 10% — Silver band indicates a tolerance of ±10%.

Tolerance — The fourth band, if present, is always the tolerance indicator, specifying the resistor's accuracy.

56 k? ± 5% — Green=5, Blue=6, Orange=x1000, Gold=5%. Therefore 56 * 1000 = 56000 ohms or 56 k?.

White — White represents the value 9 in the significant digit band.

Question 1 of 5

A resistor has the following colour bands: Brown, Black, Red, Gold. What is its resistance value?

Brown=1, Black=0, Red=x100, Gold=5%. Therefore 10 * 100 = 1000 ohms or 1 k?.

Question 2 of 5

Silver band indicates a tolerance of ±10%.

Question 3 of 5

The fourth band, if present, is always the tolerance indicator, specifying the resistor's accuracy.

Question 4 of 5

Green=5, Blue=6, Orange=x1000, Gold=5%. Therefore 56 * 1000 = 56000 ohms or 56 k?.

Question 5 of 5
