In physics, Ohm's law says that current through a wire, I, is directly proportional to voltage, V, and inversely proportional to resistance, R

I = V/R.

It's also true that resistance is directly proportional to the length of the wire. We have a piece of wire. We pass 50 volts through this wire and measure 300 milliamps of current. If I cut the wire in half and pass \(800\) volts through it, how many milliamps of current will I measure?

You will measure 750 milliamps.
