In an alternating current, do electrons flow from the source to the device? Let''s go back to DC for a second. A battery has two ends. A light bulb has two contacts. The battery won''t light the light bulb unless you make a closed circuit, so yes, electrons flow from the source to the device, and they also flow back.
Why does battery generate less terminal voltage difference when current ...
Some reasons the voltage of a battery goes down under load: Internal resistance. A simplistic first-order model of a battery is a voltage source in series with a resistance. As you draw current, the current causes a voltage across the resistance. That voltage subtracts from the internal voltage source to give you what you get on the terminals.
