Engineering Units, Energy, and Color Codes 1) Engineers use circuit design software so they can efficiently test and see if there are any potential problems. 2) Basic processing and accurately recover and store digital data. 3) An oscillator is a circuit that generate a continuous output, but differs from other circuits because the output is internally generated, but the device generating the output is considered an active device. 4) A carrier is a high-frequency signal with a low-frequency carrying the information of interest, by modulating or varying the amplitude of the higher frequency. 5) a.3, 000 a.3 x 103 b.75, 000 b.7.5 x 104 c.2, 000,000 c.2 x 106 6) a. 2.5 x 10-6 a. .0000025 b. 5.0 x10-2 b. .05 c. 3.9 x10-1 c. .39 7) a. 10V b. 2.5V c. 4V 8) 5V 9) 20V 10) 30J 11) 12.5V 12) 4A 13) a. 75A b. 20A c. 2.5A 14) .2A 15) 2s 16) 15c 17) a. 680M Ω b.33Ω c.1.3GΩ 18) a. ±10% b. ±10% c. ±5% 19) 330Ω = B 2.2kΩ = D 39kΩ = A 56kΩ = L 100kΩ = F 20) a. 365kΩ ± 2% b. 2740Ω ± .25% c. 72500Ω ± 5% 21) a. 10 Ω ± 5% b. 5.1mΩ ± 5% c. 68Ω ± 5% 22) a. yellow, violet, silver, gold b. red, violet, yellow, gold c. green, brown, green, gold 23) a.28700Ω ±1% b. 60.4Ω ±1% c. 9310Ω ± 1% 24) a. black, yellow, violet, gold, brown b. orange, white, red, gold, brown c. white, violet, blue, silver, brown 25) a.22Ω b. 4.7kΩ c. 82kΩ d. 3.3kΩ e 56kΩ f.
