Problem 3
To determine the rated component and the guaranteed range of measured values for each color code list given, we need to outline the colors' digits, multipliers, and percentage tolerance from a standard resistor color code chart.
Yellow–Orange–Silver–Gold
Yellow – 4 (1St digit)
Orange – 3 (2nd digit)
Silver – 0.01 (Multiplier)
Gold – 5% (Tolerance)
Rated component value
= Significant digits * Multiplier
Significant digits = [(1ST digit*10) + 2nd digit]
= [(4*10) + 3]
= 43
Significant digits * Multiplier = 43*0.01
= 0.43 Ω
The rated component value is 0.43 Ω
Guaranteed range of measured values
Tolerance value = Resistance value * Tolerance band value
= 0.43 Ω * 5%
= 0.43 Ω * 0.05
= ±0.0215 Ω
Maximum measured value
= Resistance + Tolerance
=0.43 Ω + 0.0215 Ω
= 0.4515 Ω
Minimum measured value
= Resistance - Tolerance
= 0.43 Ω - 0.0215 Ω
= 0.4085 Ω
The guaranteed range of measured values is 0.4085 Ω to 0.4515 Ω
Brown–Gray–Yellow–Red
Brown – 1 (1St digit)
Gray – 8 (2nd dig...
