Resistor Color Code
• Color code used to deduce resistance values:
R = (first-color number) (second-color number)
 10third-color number
– The first digit of the resistance is given by the color band
closest to the end of the resistor
– The fourth color band gives the tolerance
• Silver = 10%
• Gold = 5%
• No fourth colored band:
tolerance = 20%
• Fifth band indicates
reliability rating (optional)

• Meter innards
(from Student Manual for The Art of Electronics, Hayes and
Horowitz, 2nd Ed.)
• How to make/use an ammeter
– Provide “shunt” (parallel)
resistance to the “meter
movement” (guts of the meter)
– Place ammeter in series with circuit
• How to make/use a voltmeter
– Provide series resistance
to the meter movement
– Place voltmeter in parallel with circuit
