Inductor energy storage
Feb 2, 2018. #17. Cubrilo said: Inductor energy storage cannot compete capacitor in principle (if you think of it) due to its "dynamic nature" - it needs current to run so electrons are colliding all the time producing losses in the conductor, whereas capacitor needs just a tiny leakage current to stay charged.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery.

Energy storage in capacitor banks
Energy storage capacitors are commonly modeled as lumped RLC (resistor-inductor-capacitor) circuits. Here, equivalent series resistance (ESR) represents the resistive and dielectric losses in the capacitor, and equivalent series inductance (ESL) represents the inductance of the capacitor lead and current path through the capacitor.
6.200 Notes: Energy Storage
Just as the capacitor''s time constant indicated that with an infinite resistor across it, the capacitor would never discharge, the inductor''s time constant τ = L/R tells us that if R = 0, the inductor will never de-flux, i.e. a current will persist in the wire forever.2 2 This so-called persistent current is a key feature of ...
