    2 * 10 ^ 20 charges move in a wire when we connect a 3.7 V battery. Ho

    thanks, i forgot to calculate with electron's charge

    W=Q*V 2*10^20 Q * 3,7 V= 7,4*10^20 ??

    A copper wire contains 3.0 *10 ^ 22 number of charges on 1 meter wire

    this is the question: A copper wire contains 3.0 *10 ^ 22 number of charges on 1 meter wire. What speed do the electrons move when there is 2 A current in the wire.

    A copper wire contains 3.0 *10 ^ 22 number of charges on 1 meter wire. What speed do the electrons move when there is 2 A current in the wire. t=q/t=3,20*10^3 C/ 2.0 A = 1,5*10^22 s v= 1m/1,5*10^3s= 6,6*10^-4 m/s
