--- title: "Ohm's Law" type: concept related: [Voltage, Current] source: https://www.jemoka.com/posts/kbhohm_s_law/ confidence: high status: active --- \begin{equation} V = IR \end{equation} where, \(V\) is the voltage across the resister, \(I\) the current, and \(R\) the resistance. power (physics) the rate at which electrical energy dissipates into heat is called power: \begin{equation} P = IV \end{equation} where, \(P\) is power, and \(I\) the current, and \(V\) the voltage. Alternate formulation of power: \begin{equation} P = I V = \frac{V^{2}}{R} = I^{2} R = \dv{E}{t} \end{equation}
