Short Answer: Because metal rods are conductors. This means that while they easily accept a charge, they also easily discharge. Thus, any charge that is applied to it will immediately discharge, resulting in zero potential. Long Answer: Search for 'tiboelectric series', 'electrostatics', and 'properties of conductors and insulators'. An in-depth answer would require a collegiate-level introduction to Physics and Calculus.
Lightning is basically the precursor of an electrical discharge -- positively-charged particles neutralizing negatively-charged in a violent manner. Before the charges neutralize, they travel a long distance through a high resistance (moist air). The heat of the current through the high resistance is so intense that the resulting radiation can be visible as the light in the night sky. Moving charges is electricity.

The process is called grounding. Many devices need to be grounded, hence the U shaped pin on a devices that make contact with the ground in normal house wiring.

A discharge coefficient is used to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation.
one condition for the above question is either conductor or magnetic field must be rotating.considering rotating field and stationary conductor,the magnetic flux will be cut up by conductor resulting in the induced emf in the conductor.
Normal waxy discharge from the human ear is clear, cloudy, or a bit yellowish. Waxy discharge that is blackish or dark is a sign that there may be a current or reoccuring ear infection that is resulting in blood mixing with the normal discharge.
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.

You should never cut a live conductor. If it's a single conductor, you may be subject to a shock hazard to earth (ground). If it's a pair of conductors, then you will be creating a short circuit and may be burnt by the resulting arc.
