In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
How can the flow of electric current be started and stopped?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
Why is an energy source needed in order to have a working electric circuit?
Ultimately this is a special case of the Second Law of Thermodynamics.In the case of an electric circuit, consider Ohm's Law. Without a voltage, you will have no current. Also, if a current flows, keeping up the voltage requires power.
Why electric current current exist if an electric circuit is broken?
well, current is the movement of free electrons so if you break a point in the wire you effectively stop the electrons from flowing as the electrons need to be touching each other in order to pass on energy or charge. The reason why if there is a gap in the circuit the electrons dont just jump it is because of resistance of air as the electrons in air are not free to flow they are not conduction electrons unlike in a metal such as copper wire.
Why do electrons produce an electric field?
Some fundamental particles in nature, happened to have an electric field. We just named one of them "electron". That's the simple answer. From an engineering point of view, there is no such thing as an electric field or electric line of force. Its a classical physics construct that we came up with, in order to explain what happens when charged particles interact with each other. Why do some particles have charges in the first place? Its because of some complex quark level interaction that I don't yet understand. Thus we have positive and negative charges, which attract each other, while like charges repel and we made up "electric lines of force" to explain them.
What does an electric current need in order to flow?
negative charge
What is produce by the electric current in order to overcome resistance?
Mass
What is expended by the electric current in order to overcome resistance?
energy
What is encountered by the electric current in order to overcome resistance?
heat
What does the energy carried by an electric current depend on?
The energy carried by an electric current depends on a conductor in order to flow. an Insulator disrupts the flow
What is produced by electric current in order to overcome resistance?
Ohms law
How can electric current change?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.

What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
Methods of execution in the US?
Here are the modern ways of execution in the USA by order of usage Lethal Injection Electric Chair Gas Chamber Firing Squad Hanging
What is the mathematical equation to find electric current?
Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.
