# 1.1.4.a component identification

```Activity 1.1.4 Component Identification
Procedure
1. Using Activity 1.1.4 Component Identification posted on course website (wardende.weebly.com),
determine the nominal resistance value for the following components. Express your answers
using the proper SI units and prefix.
(Yellow / Violet / Red / Gold)
Ra = ____________________________
(Brown / Red / Green / Gold)
Rc = ____________________________
(Green / Blue / Yellow / Gold)
Rb = ____________________________
(Red / Violet / Brown / Gold)
Rd = ____________________________
(Blue / Gray / Orange / Gold)
Re = ____________________________

2. Obtain 6 random resistors from your instructor. Using the Resistor Color Code Diagram, record
each resistors nominal value and tolerance range. Next, use a digital multi-meter (DMM) to
measure and record the actual resistance value of each resistor. Finally, indicate if the measured
value is within acceptable tolerance.
