thanks, i forgot to calculate with electron's charge

Q is charge. What do you mean?

2Q?

the unit is Q

2*10^20

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

thanks

the charge is I=2,0A

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
