Why is grounding important?
Every electrical system should be earthed to get a low resistance path for dissipation of current into the earth. Major accidents take place because of improper equipment earthing or leakage current. Earth fault current directly affect the human safety. Earthing should be measured at regular intervals so as to ensure that the resistance of the earth is maintained minimum. Its main purpose is to minimize the risks of fire and shock hazards.
What is meggameter?
I've never heard of a meggameter. However, since the question is under the heading of Electrical Troubleshooting, I'm assuming that you are referring to a megohmmeter. A megohmmeter is a testing device that measures the resistance of insulators and insulation of electrical conductors. Since their resistance is generally very high, this device uses a voltage between 500 and 2000 volts at a fixed current. This combination can detect minute pinhole leaks in conductors that are not visible to the human eye. These pinhole leaks can cause arcing and eventually an electrical short.
Why does resistance of human body decrease to electricity when body is wet?
If you increase resistance, current is restricted (river is damed up). If you decrease restistance, current flows faster (river is wide and open). With water on our skin the current can travel across our skin instead of having to move through our bodies. The current has found a new path. Not inside our bodies but outside our bodies where there is much less resistance. Which is better? A large highway with a traffic jam or the side road next to the highway with the traffice jam The side road is effected by the traffic jam, but is still faster than the highway.
What is tower footing resistance?
footing resistance is that resistance which could not harm human body while touching tower...and it is calculated by earth resistance tester
How you get an electric shock?
Why Electricity shocks us:Electricity shocks us, because it is an outside force that interferes with the internal electricity our bodies' nervous systems generate.
Which parts of a human body have highest resistance?
skin
How does the body conduct an electrical current?
The human body is over 70 percent water. The electron transfer that is the fundamental part of an electrical current uses ions dissolved in solution to conduct the electrical current.
In spite of having too much resistance why does current pass through the body?
Are you under the impression that water has "too much resistance" to electrical current? If so, I can't really explain this to you. The biggest substance one could point to in the human body is water. It's almost literally what a human body is made of. For this reason, human bodies conduct electricity extremely well. You're right to mention current instead of voltage. High voltage will stun you, but a few milliamps of current across your heart could easily kill you.

Does the amount of electrolytes in your body increase or decrease the electrical current your body generates?
electrolytesn and human bady
What level of electrical current is safe for the human body?
Less than 5 milliamps @ 110 volt.

What are electrical junctions in the human body?
Electrical junctions in the human body are where the axons of nerves (singly called neurons) send a chemical to the dendrite(s) of nearby neuron(s), said chemical creating a weak electrical current in the next neuron. These neuron to neuron junctions are called, "Synapses".

How might you Draw an analogy between the nerves in the human body and electrical wires?
nerves send a message to the brain :: electrical wires send a current to whatever they are hooked up too. A better Answer: Nerves and electrical wire both transmit electricity.
What is human body resistance to electricity if skin is wet?
human body resistance to electricity when skin is wet is 1,000 ohm and when skin is dry its resistance is 100ohm
What is the highest speed a human can survive taking into account bio-mechanics and making air resistance and other issues negligible?
Speed is not a problem, no matter how great. Acceleration is a problem.
