We can model a certain battery as a voltage source in series

We can model a certain battery as a voltage source in series with a resistance. The open-circuit voltage of the battery is 10 V. When a 120-S2 resistor is placed across the terminals of the battery, the voltage drops to 6 V Determine the internal resistance (Thevenin resistance) of the battery. Express your answer to three significant figures and include the appropriate units. A ? R = Value Units
