Homework Help: How to calculate the current of a stream of electrons

  1. Dec 8, 2016 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant 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.

    3. The attempt at a solution

    So how much charge travelled 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.
