Is lightning AC ot DC?
Lightning is neither AC nor DC, but a composition of both AC and DC.
Lightning frequencies range from 1kHz to 1GHz, where there is no frequency in DC but a mixture of both AC and DC components.
Lightning is a transient impulse and a capacitive discharge.
It has both the properties of an AC and DC signal, as it has polarity and always travels in a single direction, but its voltage is not constant.
