what’s the difference between current and voltage

Answer 1

Voltage is “how hard” the electricity is trying to move.

Current is how much is actually moving.

Say you have 10 volts, running through a 10 ohm resistor.

Current = Voltage/resistance = 10/10 = 1 amp

Now lets double the resistance, to 20 ohm.

Current= Voltage/resistance= 10/20 = 0.5 amp

You still have 10 volts, so the electricity is trying just as much, but it’s twice as hard for the electricity to go through, so only half as much actually gets through.
