Start with load resistor R<sub>L</sub> = 1kΩ, measure the voltage across source resistor R<sub>s</sub> and R<sub>L</sub>. Use Ohm’s Law to calculate the current through each resistor (the current should be the same because the resistors are in series). Using the power equation, calculate the power consumed by each resistor. Calculate the power produced (delivered) by the source. Remember the source has the same current as the resistors. Does the power produced equal the power consumed? | Start with load resistor R<sub>L</sub> = 1kΩ, measure the voltage across source resistor R<sub>s</sub> and R<sub>L</sub>.

Using series relationships, determine the current through each source and the power produced by the sources. Do this for other combinations like V<sub>CA</sub> = V<sub>CB</sub> = 3V, 4V, 5V. | Using series relationships, determine the current through each source and the power produced by the sources.
