#Physics

Topics

• Joule Heating Law
• Faraday Disk

$\displaystyle \varepsilon=\oint\vec{f}\cdot \mathrm{d}\vec{l}$

• $\displaystyle \vec{f}$ is the force per unit charge produced by the source of interest
• Take an integral along the entire path of the circuit
• Interpretable as work done per unit charge
