This document describes the steps to calculate values in a circuit with two parallel circuits in series. It shows how to calculate the total resistance (RT), total current (IT), voltages across each parallel circuit (V12, V34) and individual resistances, currents, and voltages. The key values calculated are RT = 9 ohms, IT = 1.11 amps, V12 = V34 = 100 volts, and individual voltages (V1, V2, V3, V4) ranging from 9.99 to 9.99 volts.
