Physics question, circuits

[the Mannis]

Hoping to get information from the wealth of knowledge of the SDN community. In this problem, there is a circuit with a battery of 10V that is made of 3 different different wires; copper, nichrome and silver. My question is: is the current the same for all 3 of the wires of this circuit or is it different for the different materials?

Kirchhoff's law.

What would happen if they all had different currents? 10 C/s exits the voltage source. All of it gets across wire 1. It goes on to wire 2, which only allows 8 C/s through and then wire 3, which allows 6 C/s through. In any given second, you've just lost 2 C through the second wire and another 2 C through the third wire. Energy conservation says you can't destroy charge.
