Front

Use the image with a 12V source. What is wrong with the circuit?

Back

There is unwanted resistance between the power source and the load.

Front

Use the image with a 12V source. What is wrong with the circuit?

Back

Nothing. Voltage is dropping equally across each load because they are equal resistances in series.
