But that's not the point of the post. It's the text accompanying the image. And specifically the phrase "a million volts of fiery electric current"! ARGH!!!
I know Joe Public does not care, but such a sentence causes the inner guts of those with a passing knowledge of physics to twist in an awful pain. Put simply, voltage (measured in volts) is not the same as current (measured in amps).
If you are being electrocuted, the difference may not bother you, but the fact that smoke is coming out of your ears is not an excuse for physics illiteracy.
Right. This is going to be a short post, as I have lots to do, but let's use a gravitational analogy.
Let's imagine you are on the top of a very tall building. It is a long, long way down. You have a certain amount of gravitational potential energy which is proportional to your height off the ground. Simply put, this is your gravitational "voltage".
You step off the building. Let's ignore the acceleration time, but assume you instantaneously fall at the terminal velocity in air. This is almost 200 km/h, and will probably result in a messy end. The speed at which you fall is the gravitational "current" (in reality, you want a line of people jumping off to get a real current, but let's not have that disturbing picture).
Let's consider changing the experiment slightly. We keep the height the same, so the gravitational "voltage" stays fixed, but now you jump into a tube on the side of the building filled with treacle. Again, you fall at the terminal velocity, but this is much lower.
You gravitational "current" has gone down because the "resistance" to your motion has gone up.
Is it really that difficult? If you have a journalist friend, get them to watch this all explaining video
