Getting energy from an outlet to a load: rectification, regulation, and the dissipation each method pays for.

Entries in this section 3 / 8

1. Electric PowerP = V · I

   The rate at which electrical energy is converted, equal to voltage times current.

2. Ohm's LawV = I · R

   The linear relation between voltage, current and resistance in a resistive element.

3. TransformerV₂ / V₁ = N₂ / N₁

   Two coupled windings on a shared magnetic core that trade voltage for current.
