Chapter 4: Understanding Voltage, Current, and Resistance
Voltage is like the push the electrons need to get moving in a circuit. It’s measured in volts and is sort of like the pressure in a water hose. More voltage means electrons move faster.
Current is how many electrons are zooming past a point in the circuit each second. It’s measured in amperes, or amps. Picture it as the amount of water flowing through a river.
Resistance is like the obstacles in the river that slow the flow down. It’s measured in ohms and can make it harder for electrons to pass. Things with high resistance, like a narrow pipe, slow the flow of electrons.
