Spark Gaps | How it works, Application & Advantages
The gap distance is a primary factor: a wider gap requires a higher voltage to initiate a spark. The type and pressure of the gas in the gap also plays a significant role. For instance, spark gaps filled with noble gases can handle higher voltages than those filled with air. Additionally, the shape and material of the electrodes can …

Inductor i-v equation in action (article) | Khan Academy
equation: v = L d i d t i = 1 L ∫ 0 T v d t + i 0. We create simple circuits by connecting an inductor to a current source, a voltage source, and a switch. We learn why an inductor acts like a short circuit if its current is constant. We learn why the current in an inductor cannot change instantaneously.
