# Volts and current ?

I'm confused what's the difference between voltage and current ? also what's the difference if I power a 1.5v motor with 3 1.5 battery's in parallel and same motor in 3 1.5 battery's in series

Voltageis analogous to pressure -- the higher the voltage, the more "electric flow" you get.Currentis that flow itself -- how many electrons are going through your wire per second.Voltage and current are related to each other (in the DC case) through

resistance-- how much effort does it take to get the electrons to move through your circuit/device. That relationship isOhm's Law:V=I×R.Your second question is asking about

parallelvs.series. With the batteries in parallel, you get just the 1.5V to drive the flow, but you get a total current summed over all the batteries (so three times as much current as one battery).With the batteries in series, each battery can "boost" the flow by its own voltage, so the total voltage is also tripled (4.5V).
