Electric Shock

[username]

If a very large amount of power was grounded say in house and all the taps for example were connected to the same circuit would somebody touching a tap get any sort of eletric shock. I have heard that some peoples TVs etc explode when their house gets hit by lightening even though they have proper grounding.

Proper internal grounding means nothing if the lightning is able to find its way onto the power supply wires. Read the wire specs, they are rated for 600V or less, and a few million volts sees that insulation very differently. :)

A grounded lightning rod is like a judo move - it doesn't fight the force directly but deflects and redirects the force.
