Resistors and Voltage Dividers

Voltage and current, and resistance of circuits with resistors in series and parallel. Resistor color codes: DUE_T = DU * 10^E +/- T% Where D (tens), U (ones), and E (exponent) are as follows: 0 = black 1 = brown 2 = red 3 = orange 4 = yellow 5 = green 6 = blue 7 = violet 8 = gray 9 = white And where T (tolerance) is as follows: 0.1% = violet 0.25% = blue 0.5% = green 1% = brown 2% = red 5% = gold 10% = silver 20% = none
