# A 16.50 ?? long wire has a diameter of 0.355 ?? and a resistivity of7.65 ?...

A 16.50 ?? long wire has a diameter of 0.355 ?? and a resistivity of7.65 ? 10,- Ω ??.

( a ) Calculate its resistance

(b) If a 3.85 ???? battery is connected to the wire, what current exists in the circuit?

I changed those three values to meters as below, what do I do next please

Length = 0.165 m

Diameter = 0.000355 m

Resistivity = 7.65 * 10^-9 Ω m
