# Need help parallel and sereis circuits physics?

2) Three wires connected in parallel to a battery stretch across 100 m. Each wire has a

diameter of 50 cm and a potential of 110 v across them. The current coming out of the

battery is 11.58 x 106 amps (don't touch them!). Use the resistivity table in your book to

determine what type of material makes up the wire?6 pfs

Assuming all three wires are made out of the same material

you can determine the total (equivalent) resistance of the parallel wires using V=IReq

and from there you can determine the total resistance of each wire using the parallel resistance equation.

1/Req = 1/R1 + 1/R2 + 1/R3

but since R1=R2=R3=Rwire

1/Req = 3/Rwire

Once you have the resistance of one wire

since you also have the length and diameter

you should be able to determine resistivity of a single wire

and match that to some material in the table in your book.
