Arear window defroster consists of a long, flat wire bonded to the inside surface of the window. when current passes through the wire, it heats up and melts ice and snow on the window. for one window the wire has a total length of 12.2 m, a width of 1.6 mm, and a thickness of 0.11 mm. the wire is connected to the car's 12.0 v battery and draws 7.5 a. what is the resistivity of the wire material?

The resistivity of the wire material is

Explanation:

Given that,

Length = 12.2 m

Width = 1.6 mm

Thickness = 0.11 mm

Voltage = 12.0

Current = 7.5 A

We need to calculate the resistivity of the wire material

Using formula of resistivity

....(I)

Using ohm's law

Put the value of R in equation (I)

Put the value into the formula

Hence, The resistivity of the wire material is

e) none of the above answers are correct

connect the batteries in series and hope
