[2] Relatively weak thunderstorms are sometimes called thundershowers. [3] Thunderstorms occur in a type of cloud known as a cumulonimbus. [4]

“Lightning currents could, for example, get inside the house through the electrical wiring, spark to the pipes and give you a shock while in the shower or the tub,” Joseph Dwyer, a professor ...
Lightning currents have a very fast rise time, on the order of 40 kA per microsecond. Hence, although lightning is a form of direct current, conductors of such currents exhibit marked skin effect as with an alternating current, causing most of the currents to flow through the outer surface of the conductor.
