Electricity. The electric needs to have electricity and plugged into a amp to get the sound.
The purpose of a 320 amp meter base with 2 200 amp disconnects in an electrical system is to accurately measure and control the flow of electricity entering a building. The 320 amp meter base measures the total electricity usage, while the 200 amp disconnects allow for safe disconnection of power in case of maintenance or emergencies.
Electricity is not sold by the amp, but by the kilowatt. And the cost of a kilowatt varies depending on where you are. Sorry, but there is just no one answer to your question.
The volume flow of electricity from one point to another.
A 200 amp electrical service panel can handle more electrical load than a 100 amp panel. This means it can power more appliances and devices without overloading. The 200 amp panel is typically used in larger homes or buildings with higher electricity needs, while the 100 amp panel is suitable for smaller homes or buildings with lower electricity demands.
If your talking about state, like as in states of matter, then electricity has none. Electricity is not matter, so it can not have a state.
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
Amps i believe ( if your talking about electricity)
W = watts
