This document contains calculations for 4 exercises involving voltage dividers and current dividers. In the first exercise, it calculates the total resistance, input current, and currents through each resistor in a voltage divider circuit. The second exercise calculates the total resistances and currents for two voltage divider circuits connected in series. The third exercise uses voltage divider equations to calculate the voltages at each resistor in a 3 resistor voltage divider. The fourth exercise calculates the total resistance, input current, and currents through each resistor for a current divider circuit.
