    Voltage across a load resistor in a Voltage Divider Circuit

    Homework Statement Show that V across Resistor Rkohms is: (11R) / (3.96 + 4R) V The circuit is a 5V cell in series with a 1.8k resistor. Following the 1.8k resistor are a 2.2k and Rk resistor in parallel with eachother. The wires then rejoin and return to the cell. Current through the...
