10 Questions
Question 1 of 10
Which colour represents the value '7' in the resistor colour code?
Violet represents the digit 7 in the standard resistor colour code.
Question 2 of 10
What is the tolerance represented by the gold band?
Gold represents a tolerance of ±5% in the resistor colour code.
Question 3 of 10
In a 4-band resistor, what does the fourth band represent?
The fourth band in a 4-band resistor indicates the tolerance.
Question 4 of 10
A resistor has the following bands: Brown, Black, Red, Gold. What is its resistance value?
Brown=1, Black=0, Red= x100, Gold=±5%, Therefore 10 x 100= 1000 ohms.
Question 5 of 10
What colour represents a multiplier of 1000 in the resistor colour code?
Orange represents a multiplier of 1000 (10^3) in the colour code.
Question 6 of 10
Which band's position helps to identify the resistance value beginning side?
The tolerance band is usually offset more to help identify the beginning side.
Question 7 of 10
What is the tolerance value of a silver band?
Silver represents a tolerance of ±10% in the resistor colour code.
Question 8 of 10
What is the maximum number of bands on a resistor?
The most common and highest bands a resistor has is 6.
Question 9 of 10
Which colour indicates the digit '0' in the resistor colour code?
Black is used for the digit '0' in the resistor colour code.
Question 10 of 10
A 5-band resistor has the following colours: Red, Red, Black, Black, Brown. What is its resistance?
Red=2, Red=2, Black=0, Black= x1, Brown=±1%, therefore 22 x 1 = 220 ohms.
