* Voltage is the driving force: Voltage is the electrical potential difference between two points in a circuit. It's what pushes the electrons, creating the flow of current. Think of it like a water pressure difference in a pipe – the pressure difference makes the water flow.
* Current is the flow of charge: Current is the rate at which electric charge flows through a conductor. It's the actual movement of electrons.
* Ohm's Law: The relationship between voltage, current, and resistance is defined by Ohm's Law: V = I * R.
* V = Voltage
* I = Current
* R = Resistance
This law shows that voltage is directly proportional to current. If there is no voltage, there is no force to drive the electrons, and therefore no current.
Think of it this way: Imagine a river. The water flow (current) is dependent on the difference in height (voltage) between the source and the destination. If there is no difference in height, there is no flow.
