# Really confused about voltage and some other quetions

• I

## Main Question or Discussion Point

Please explain how or why (I have zero knowledge in physics)..

1. is Voltage the energy required by the elctrostatic forces between 2 points to move a certain quantity of charge between them?

2. Why is it called potential difference? Does this have to do with the difference in potential energy between two regions of opposite net charges? Why? In mechanics as I learned potential energy is the energy an object has due to its shape or position (change in PE= Change in H * G*M), what does this mean in a circuit?

3. Current, when the current is of a higher magnitude, do the electrons flow faster within a certain imaginary plane at a given time or just that there are are more electrons? does the speed of current vary in a circuits?

4. If resistance in a circuit is zero, does this mean there can not be any voltage? V = I * R and the multiplicative property of 0. Or is it not possible to not have 0 resistance?

5. What is meant by thsi statement "IN engineering the current direction describes the net positive flow"?

6. Is thE " WORK DONE" to move one charge to another region of net opposite charge given by multiplying the ([Q1*Q2/R^2]*k)* distance between the charges? what does this have to do with voltage?
