Answer:
Explanation:
The relationship between the current and the electric field inside a wire is given by the following equation:
where ρ is the resistivity, and J is the current density. The current density is the current per area:
The resistivity is the reciprocal of conductivity. Therefore,
Finally, the electric field can be found:
Conduction:
The handle of a pot becoming too hot to grab as it cooks on the stove.
Grabbing a warm coffee mug to warm your hands.
Putting an ice pack on an injury.
Burning yourself by touching boiling water.
Convection:
An oven that cooks by cycling warm air through the bottom and out the top.
Warm water rising to the surface of the ocean and cooler water sinking.
Cooking popcorn using a microwave.
Radiation:
Heat from a fire warming your hands.
Warm air rising off of the pavement.
Heat from the sun hitting a solar panel.
