How to calculate the current of a stream of electrons

Click For Summary
To calculate the current of electrons from Io to Jupiter, the formula I = Q/t is used, where Q is the total charge and t is the time period. Given that 2.6 × 10^26 electrons reach Jupiter in 15 seconds and each electron has a charge of 1.6 x 10^-19 coulombs, the total charge can be calculated by multiplying the number of electrons by the charge of a single electron. After determining the total charge, it is divided by the time to find the current. This method effectively relates the charge of electrons to the current flowing towards Jupiter.

Homework Statement



The planet Jupiter has a moon Io. Volcanic activity on Io releases clouds of electrons which travel at high speeds towards Jupiter.

During a 15 s time period, 2.6 × 10^26 electrons reach Jupiter from Io.

Calculate the current.

Homework Equations



I know current I = Q/t and that an electron has charge 1.6 x 10^-19 but I don't know how to relate this to the question. Can someone explain this to me please.

Yes.
So how much charge traveled to Jupiter from Io in how much time?

doh! so we have 2.6 electrons and each electron has charge of 1.6 coulombs, so the current is: charge (electrons x charge) divided by time. Got it.

Thanks!
 
Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
