390k resistor
Alternative 1
The color code for the 390k resistor is:
ORANGE = 3
WHITE = 9
BLACK = 0
ORANGE = 3 (3 zeros in this case)
BROWN = 1 (1% Tolerance)
= 3 9 0 0 0 0 with 1% tolerance
Alternative 2
The color code for the 390k resistor is:
ORANGE = 3
WHITE = 9
YELLOW = 4 (4 zeros in this case)
GOLD = 5% Tolerance
= 3 9 0 0 0 0 with 5% tolerance
2.7k resistor
Alternative 1
The color code for the 2.7k resistor is:
RED = 2
VIOLET = 7
BLACK = 0
BROWN = 1 (1 zero in this case)
BROWN = 1 (1% Tolerance)
= 2 7 0 0 with 1% tolerance
Alternative 2
The color code for the 2.7k resistor is:
RED = 2
VIOLET = 7
RED = 2 (2 zeros in this case)
GOLD = 5% Tolerance
= 2 7 0 0 with 5% tolerance
