You may have heard of watts, volts, and amps, but do not know the difference between the three.  Think of water flowing through a pipe. Amps would be the volume of water flowing through the pipe. The water pressure would be voltage. Watts would be the power (volts x amps) the water could provide for things like powering a building. Think of the old water mills they used to use for power. This ties into the #StarBattery project because they need to know how many watts/volts they need to charge a phone.

                     

This relates to engineering because people doing anything that involves powering something like a home needs to know the difference between amps, watts, and volts. Electrical engineers deal with this kind of knowledge everyday. They wouldn’t be very successful if they did not know the difference between amps, watts, and volts.
