Activity 1.1.4 Component Identification

Procedure1. 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)(Green / Blue / Yellow / Gold)

Ra = ____________________________ Rb = ____________________________

(Brown / Red / Green / Gold) (Red / Violet / Brown / Gold)

Rc = ____________________________ 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.
