# Air Conditioner#

The current supplied to an air conditioner unit is 48 $$\textrm{A}$$. The air conditioner is wired using a 10-gauge (diameter 2.588 mm) wire. The charge density is $${{{params.n}} \times 10^{28}} {electrons \over m^3}$$.

## Part 1#

What is the magnitude of the current density?

## Part 2#

What is the magnitude of the drift velocity.

$$J=$$ $$\rm\ {A/m^2}$$
