Please help, and provide the corrects answers. It will bring my grade up.?

These questions are really quite basic. I think it would do you well to research and answer them yourself.

b, d, b.
You should probably look up the definitions of all the technical terms you have not understood.

The only one of these questions that presents any ambiguity is #2, because in fact a circuit IS a conductor (of sorts), but not every conductor is a "circuit." The word "circuit" implies a specific looped path.

To get a general feeling that you understand electricity, try to think of it as the flow of water through pipes. The wires are the "pipes", and the water flows from high pressure to low pressure (and the electric potential is the "pressure" created by a battery or other power source).

Hello Eugene

Alright, here goes...

How does electricity flow?

Truth is that there are two possible answers, One is called the Conventional System where current flows from the Higher potential to the Lower potential.
In reality, electric current being the flow of electrons through a conductor, and electrons having a negative charge and like charges repelling each other, it becomes obvious that electricity flows from a Lower potential to a Higher potential by the equally important observation that unlike charges attract each other.

What is a circuit?

A circuit is an unbroken loop of conductive material through which current flows continuously.

Lights strung together in a line along a circuit would be an example of a __________ circuit.

In the space occupied by the dotted line, use the word series.

All the best
