Question

A carbon resistor is marked in colour bands in the sequence blue green orange and gold what is the resistance and tolerance value of the resistor

Answer 1

Answer:

A carbon resistor is marked in colored bands of red, black, orange and silver. So, the value of the resistance is 20,000 Ω with 10% tolerance.

Answer 2

$\Large{\textsf{\pink{\underline{ANSWER}}}}$

★ The resistance can be calculated as per the color code of the respective bands.

Blue - 6

Green - 5

Orange - 3

★ The first two bands gives us the significant numbers and the third band gives us the decimal multiplier.

▶Therefore,

Resistance, R = 65 x 103 Ω ± 5%.

where, 5% is the tolerance of gold.
