How To Remember Resistor Colors (Mnemonics)
The international color sequence is: Black (0), Brown (1), Red (2), Orange (3), Yellow (4), Green (5), Blue (6), Violet (7), Gray (8), White (9). Use these classic mnemonics:
“Better Be Right Or Your Great Big Venture Goes Wrong”
Black (0), Brown (1), Red (2), Orange (3), Yellow (4), Green (5), Blue (6), Violet (7), Gray (8), White (9)
“Bad Boys Race Our Young Girls But Violet Generally Wins”
