In this project, we built a DIY inline USB-C power meter that measures voltage from 5 to 28 V and current up to 5 A. It also tracks charge and energy consumption, records minimum, maximum, and average readings, and displays a rolling 30-second graph of voltage, current, and power on a colour IPS display.

UNDERSTANDING CURRENT, VOLTAGE AND POWER
http://www.smps.us –
The purpose of electronic circuits is to control the flow of electric currents. This may sound like a silly question, but why do we need to control the currents? Well, it has been found experimentally that the intensity of various electrical effects is related to the amount of the charge Q that passes by a certain region per unit time.
