Drag the labels to the steps to identify their proper order when determining the total current through R1 in the circuit using the Principle of Superposition if values for E1, R1, and E2 are known. Click on the image to view a larger version of it. a. Repeat for all sources. blank b. Remove one source and replace it with a short. blank c. Use Ohm's Law to determine the current in R1 caused by that source, including polarity. blank d. Solve for total current in the load resistor by summation.
