1. What is going on in a wire conductor with free electrons?
2. What do you have to calculate to get the amount of electrical power?
Stands for direct current and it is when electrons move in one direction.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
You must multiply voltage ( involts) times current(in amperes).
3. What does the positive-negative attraction relate too?
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.
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
From an electricians - pov - electricity is the movement of electrons. Electrons are atomic particles found in every substance. An electron has one main characteristic which is a negative electrical charge.
