From top to bottom:
* Green, blue, black, black, brown
** 560&nbsp;ohms ±1%
* Red, red, orange, gold
** {{val|22000|u=ohms}} ±5%
* Yellow, violet, brown, gold
** 470&nbsp;ohms ±5%
* Blue, grey, black, gold
** 68&nbsp;ohms ±5%

The physical size of a resistor is indicative of the [[power (physics)|power]] it can dissipate.

There is an important difference between the use of three and of four bands to indicate resistance. The same resistance is encoded by:
*Red, red, ''orange'' = ''22'' followed by ''3'' zeroes = {{val|22000}} (excluding default, silver, or gold tolerance)
*Red, red, ''black'', ''red'' = ''220'' followed by ''2'' zeroes = {{val|22000}} (excluding brown or other band for tolerance)
