I couldn't for the life of me work this out.
I was given 4 choices:
A) kgms-2
B) kgm2 s-1
C) kgm2 A-1 s-1
D) kgm2 A-2 s-3
After searching online, I came across the answer being D, with the explanation of Ohm = volt/amp = m2 kg / sec3 A2
What I don't understand is how, in an exam situation, I would go about trying to answer it?
I don't believe either in the revision guide or text book it mentions the base units for either volt or amp and the definition of them (whether worded or as an equation) doesn't seem to help me figure out their base units, so how would I be able to work out what they were?
