Who invented amperes?
Nobody. They have been around as long as lightning strikes. There are no ampheres unless voltage is present and moved through a circuit. Who named it? Amphere maybe. ?
What is power frequency withstand voltage test?
A test done on a transformer. The voltage at the power frequency is ramped up to verify the transformer is capable of handling the stresses due to switching and natural phenomena (lighting strikes).Withstand Voltage:The voltage which has to be applied to a test object under specified conditions in a "withstand test" is called the "withstand voltage".
Why does the electricity go out when it is storming?
Storm related electrical outages may occur for a variety of reasons, most of which are caused by lightning strikes, fallen trees, or weather related damage to the components of the electrical system. If a major storm produces severe flooding, the local electrical power may be turned off to prevent accidental electrocution and to prevent damage to the main electrical grid infrastructure.
How much power is 4 MW?
4 megawatts - heaps The megawatt is equal to one million watts. Many events or machines produce or sustain the conversion of energy on this scale. For example: lightning strikes, large electric motors, naval craft (such as aircraft carriers and submarines), engineering hardware, and some scientific research equipment, such as supercolliders and large lasers. A large residential or commercial building may consume several megawatts in electric power and heat.
What are the round ball like structure on the topmost line in power transmission lines?
The topmost conductor in a transmission line is called the guard conductor; it is an earthed (grounded) conductor that links the metal support towers. Its function is to protect the transmission lines against lightning strikes. The coloured balls that are sometimes seen distributed along the guard conductor are intended to make the lines easier to see in those areas where aeroplanes might be flying -they are often seen on lines in the vicinity of airfields. They are also used in areas, such as nature reserves, to make the lines visible to large birds.

Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
How many strikes in strike out?
