    Hi everyone
    I’m really stuck on a physics question
    Would someone mind explaining it to me
    The question:

    5.4 x 10^21 electrons flow through an appliance in 3 minutes
    A) how much charge flows through this appliance
    B) what is the current drawn by this appliance

    I am familiar with the equation Q=I*T but that doesn’t seem to be helping me because only know the time
    Please leave any help down below

    Many Thanks in advance

    What you need is the charge of a single Electron ( 1.60 x 10^-19 C) with that you’ll be able to complete part a, in turn part b
