Energy storage

Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.

The effect of an inductor in a circuit is to oppose changes in current through it by developing a voltage across it proportional to the rate of change of the current. An ideal inductor would offer no resistance to a constant direct current; however, only superconducting inductors have truly zero electrical resistance. The relationship between the time-varying voltage v(t) across an inductor wit

In this case, the primary coil is energized to operate the relay, and the secondary coil is short-circuited inside the case. When the current through the primary is interrupted, as happens when the relay is switched off, most of the magnetic energy is intercepted by the secondary coil, which converts it to heat in its internal resistance.

All other factors being equal, a greater number of turns of wire in the coil results in greater inductance; fewer turns of wire in the coil results in less inductance.

greater the primary resistance, the lower the current (and available energy). In a CD ignition, the resistance is not nearly as important, but contributes to the parasitic losses as the peak current goes up. Primary resistance is a combination of two things: the coil''s primary winding resistance and the external ballast resistance (if used).

What does the ''resistance'' of a coil mean?

If you''re using a more modern battery/mod but it does not have adjustable wattage, your device will usually automatically read the resistance of your coil and output a wattage suitable for that coil. All batteries/mods have a minimum and maximum coil resistance that they can work on, known as an atomiser resistance range, e.g 0.15Ω - 2.0Ω.

Does a coiled wire have a higher resistance than straight wire?

Everyone so far seems to have forgotten (or not heard of) proximity effect. Ignoring the inductance of a coiled wire and only concentrating on losses i.e. the resistive part of the wire then, at DC there will be no change. However, as frequency increases proximity effect between the coils will certainly increase the resistance of a conductor.
