ISAAC Physics help - its given me a headache :)Watch
for part A i figured:
I = nAve
n = 6.24*10^8
v= 5 m/s (given in the question)
and e is the elementary charge
but how do I work out A?
Is this the right approach?
Part B baffled me i didn't know what ideas to put down
And in part b, its pretty much the same thing but this time you have to the protons positive charge which cancels out some of the electrons negative charge so the overall current will be less
