Why do people have to turn on and off the flow of electrical current?
The need to turn it on when they want the electrical energy to do something for them and need to turn it off again afterwards.
Is a north or south magnet in a compass a permagnet or an electromagnet?
That's a permanent magnet. After all, the compass doesn't need an electrical current, right?That's a permanent magnet.

How does a coil of wire create a electrical current?
By itself, it won't. To have an electrical current, you need a voltage. This voltage might be applied externally, or it might be induced by movement of the wire through a magnetic field (or by a changing magnetic field).
What type of energy is carried by moving negative charges?
That is the electric energy. It is called the electricity
What quantities are needed to calculate an object's resistance?
Voltage, current, or power. You need two out of the three.
What three things do you need for electric current?
protons,neutrons and electrons
What things need a electrical circuit?
Electrical devices need an electrical circuit.
What did alternating electrical current effect in the 1920?
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
Why do people have to turn on and off the flow of electrical current?
The need to turn it on when they want the electrical energy to do something for them and need to turn it off again afterwards.
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
What is the car current amp's consumptions need?
The current use all depends on what electrical fixtures or accessories are being used.
Why are there fuses for the transmission?
Because all electrical circuits need over-current protection.
How do you know if there a current?
Do you mean water current? Do you mean electrical current? I'm not sure really what you're asking. You need to be specific. Either way, don't stick an electrical wire into water to check the current as you may die. It's not a healthy test.
What are three things that need to be cleaned by water?
the three things that need to be cleaned from water are chemicals,germs
Does electrical current increase as voltage increases?
Electrical current generally increases as voltage increases due to a need for increased capacity. This is directly controlled from the transmission side but varies based on the overall load.
What are the three things electronic hardware devices need in order to function?
An electrical system to provide power It needs software to instruct the device A method for the CPU to communicate with the device
