1. What does the positive-negative attraction relate too?
Energy
Most common electrical devices are set to operate as 120/240 V.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
2. What happens when current passes through a motor's field coils?
A magnatic field is generated that makes the motor rotate - producing mechanical power.
Electrons can be forced to move by pushing more electrons to the wire. However - no electron can get into the wire unless an equal number of electrons is pushed out of the other end.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
3. What is the basic unit to measure electrical power?
120/240 V service.
Watt.
Stands for direct current and it is when electrons move in one direction.
Electrons can be forced to move by pushing more electrons to the wire. However - no electron can get into the wire unless an equal number of electrons is pushed out of the other end.
4. What is voltage or electromotive force?
Amps or just A - is the measurement in units of the amount of electric current that flows. The rate of electron flow determines the number of amperes in a circuit. The rate of electron flow determines the number of amperes in a circuit.

Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
6. What do you have to calculate to get the amount of electrical power?
In a wire conductor - there are billions of loose or free electrons - all safely in place in their fields. They're distributed evenly throughout the wire.
