I suspect that there are must be two different effects: one that causes the car to stop, which would be more or less immediate in effect, and another that dissipates after some minutes. For the immediate effect that causes the car to stop, this would most likely be electrical, such as an induced surge in the automobile's Engine Control Unit (ECU). ...
A lightning striking a car creates huge transients in all kinds of electro-magnetic fields as you go from 0 to some thousands to 0 amperes in a very short time span. My first guess would be that the fields created by the lightning interacted with some components of the car. In modern cars a of lot of electronics is used. What caused the problem exactly, may ...
Lightning gives off high current when it hits a car/vehicle, and since the electrical components of the car is grounded on the chassis, are there possibilities that these high currents can destroy or damage the electrical components,battery, antenna etc through the 'grounding'? Lightning also has a massive electromagnetic field that is created ...
If you just want a "rough" idea of how far away the lightning struck, then the answer is yes. You can use the loudness of the thunder as an indicator of the relative distance (a loud strike will be closer than a faint strike). More accuracy could be be gained with a loudness measuring device calibrated with known average strength of strikes and how far ...
The energy in a static discharge is 1/2 * voltage * charge. For a 1MV VDG with a 1 meter sphere that's approximately 1/2 * 55µC * 1MV = 27.5J However that's too much to do experiments safely. You should stay far below 1J. Also mutimeters don't like sparks or high voltages of several kV.
Why would it be any more dangerous than, say, wearing a metal wristwatch, a ring, or metal body piercing? The answer is not at all, in fact less, since most devices with a wireless device in them are surrounded by plastic, which is an insulator.
