Copper is a good conductor of electricity because its electrons are what?
The copper (the positive protons) hold the inner negative electrons securely, but the outer most negative electrons of the copper atom are easily disloged and become free electrons, apply a potential difference (volts) between terminals of say a car battery, and the terminals are joined by copper wire then electrons will flow from one terminal to the other - the electron flow is from negative to positive terminal.Hope this helps I have just answered the question simply!
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Which particles moves when an object acquires a net positive or negative charge?
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.
How current flow from positive to negative terminal in cell?
DC current. Some experts argue that indications show that electrons flow from negative to positive (According to current arguments), but it is assumed generally that electrons flow from positive to negative.
Why electrons flow in negative to positive direction?
Electrons are negatively charged particles. The reason the negative side of your D battery is negative is because that's where the free electrons are. The positive terminal is starved or has a deficit of electrons. The negatively charged electrons naturally want to fill the 'holes', in atoms lacking an electron on the positive side. Thus electron flow is from negative to positive. Conventional current flow assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong!
Why do electrons move from negative end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.
Why do electrons move the negative end of the tube to the positive end?
Electrons move from the negative end of the tube to the positive end because they are negatively charged particles that are attracted to the positive charge. This movement creates an electric current in the circuit.
What is the driving force for the flow of electrons in battries?
The driving force for the flow of electrons in batteries is the potential difference, or voltage, created between the positive and negative terminals. This potential difference causes the electrons to move from the negative terminal (anode) to the positive terminal (cathode), creating an electric current.
Why do electrons move from the negatively end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.
Why do electron move from the negative end of the tube to the positive end?
Electrons have a negative charge and are attracted by the positive end.

What is the effect of the reverse bias on the width of the PN junction?
The holes and electrons move away from the junction and attracted towards the terminals as the positive polarity is connected to the n-side and negative polarity to p-side.
What kind of charge can move from object to object?
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
Which particles moves when an object acquires a net positive or negative charge?
Electrons are the particles that move when an object acquires a net positive or negative charge. In the case of a positive charge, electrons are removed from the object, leaving an excess of positive charge. Conversely, in the case of a negative charge, electrons are added to the object, creating an excess of negative charge.
In a wet cell electrons move from the negative electrode to the positive electrode?
In a wet cell, such as a battery, the negative electrode is where oxidation occurs, releasing electrons. These electrons flow through an external circuit to the positive electrode. At the positive electrode, reduction occurs, and electrons are accepted back, completing the circuit.
What does a battery positive and negative diagram illustrate?
A battery positive and negative diagram illustrates the flow of electric current within a circuit, showing the direction in which electrons move from the negative terminal to the positive terminal.
