Calculate the potential difference across a 25-Ω resistor if a 0.3 current is flowing through it. If you could show me how to do it too that would be great too thanks.

Surely you've seen Ohm's Law: V = I * R. My guess is you just learned it. You were given I and R, so plug them in.
Numbers in physics have units by the way. I'm guessing that "0.3 current" was actually "a 0.3 Amp current".
