what’s the difference between current and voltage
In: 9
So current is just moving charges. Current is charge/unit time. Its how many charges move from A to B in one second for instance.
Voltage is potential energy. When you got a voltage it means that you have an electric potential difference. Lets look at a simple battery. A battery converts chemical energy into electric energy. The two ends of the battery point A and point B. So if there is a potential difference between A and B there is a potential for a current. All that means is that energy is available for a current to start.
One you connect the two ends of the battery charges will flow.
To look at a simple equation its Ohm’s law. R=U/I. R is the resistance of your wire for instance U is voltage and I is current. If you increase U and R stays the same I must increase. Which makes sense the more energy you got for a current you’ll have more current.
