This comparison exercise provides an analogy between
- water flow with electric current (electron flow)
- mechanical energy (kinetic energy) with electrical potential energy
- water pump and battery
Please give it a try by substitution of the analogies and match.
Post what you get to check your attempts.
Need help matching the numbers to a - f. I need some explanations to understand.
4. The water enters the pump at a low pressure and the pump does work on the water to eject it at high pressure and with more energy.
5. The water pump provides the motive force that pushes water through the pipes.
6. The water pump gives the water energy to move around the pipes.
7. The water current travels from one side of the pump, around the pipes, back to the other side of the pump.
8. The water current will be divided between pipes if any branches are present.
9. The water current slows down when it passes through a filter and loses some of its energy. The strength of the filter will determine how much energy the water loses.

A. Electric current travels from one side of the battery, around the circuit, back to the other side of the battery.
B. Resistors slow down electrical current and the current will lose some electric potential energy. The higher the resistance the more electric potential energy the current will lose.
C. The electrons enter the battery with a low electric potential energy and the battery does work on the electrons to eject them at high voltage and with more energy.
D. The battery gives the electrons electric potential energy to move around the circuit.
E. The battery provides the motive force that pushes electrons through the wires.
F. Electrical current will be divided between wires if there are any branches present in the circuit.
