Calculate the resistance per unit length of a nichrome wire, which has a radius of 0.436 mm. The resistivity of nichrome is 1.5×10−6 Ω·m.
Answer in units of Ω/m
If a potential difference of 20 V is maintained across a 3.7 m length of the nichrome wire, what is the current in the wire?
Answer in units of A

3.579 A
