Ellie Electron and her family are taking a trip for the holidays. They are taking a train toa cabin in the mountains.
Where are we going?
Smoky Mountains!
Hi there, have a seat. Would you like to learn about trains?
Yes please!
Ellie loves trains and wants to know more about them. She sneaks to the driver's control room where she finds the driver, Ethan Electron.
Ellie looked at the time, her ride was almost over. As they were reaching the Grand Proton Station, her parents came and found her.
Trains work like circuits. We use Volts to fuel the train and volts are energy within a circuit. Also, each railroad track only goes in one direction, just like a positive current.
Thank you for teaching me about trains AND circuits!
There you are, we were looking for you.

Ellie and Ethan said their goodbyes as she left to go to her cabin. Ellie couldn't wait to have more fun learning about trains and circuits on the ride home. The End.
Some areas of the mountain are very rocky so it slows down the train and takes more energy like resistors do to the current. Current is measured in Amps and resistance is measured in Ohms.
.
We multiply the resistance of the path by the current of the railroad. If there is more than 1 rocky resistor, we can add all resistances on this path to figure out how much fuel I need, just like a series circuit
How will you know how much fuel you need if there are so many rocky resistors on the path?
