- Electric charge is a fundamental property of matter that can be positive, negative, or neutral.
- Like charges repel each other, while opposite charges attract.
- Electric charge is conserved, meaning it cannot be created or destroyed, only transferred from one object to another.

What is the direction of the electric field near a negative charge?
The electric field near a negative charge points radially inward towards the charge.
What direction does the electric field point at a position directly east of a negative charge?
The electric field points toward the negative charge.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
The electric field around a negative charge points inward, towards the charge, while the electric field around a positive charge points outward, away from the charge. The electric field strength decreases with distance from both charges, following an inverse square law relationship.
What is the definition of potential defference?
Potential difference is the difference in electric potential between two points in an electric field. It is measured in volts and represents the work done per unit charge in moving a test charge between the two points.
In which direction does the electric field point at a position directly north of a positive charge?
The electric field points directly away from a positive charge. Therefore, at a position directly north of a positive charge, the electric field would also point directly away from the positive charge.
What is the direction of the electric field near a negative charge?
The electric field near a negative charge points radially inward towards the charge.
If the electric field due to the excess charge on the Earth points downward what type of charge does the Earth carry?
The Earth carries a negative charge, as the electric field due to excess negative charge on the Earth points downward.
The electric field of a point charge always points away from the charge?
Yes, the electric field of a positive point charge always points away from the charge, radially outward in all directions. Conversely, for a negative point charge, the electric field points radially inward toward the charge.
What direction does the electric field point at a position directly east of a negative charge?
The electric field points toward the negative charge.
Where would you charge an electric car?
There are many places where one is able to charge an electric car. Most people tend to charge at home. However, there are three different types of charging stations. Typically, these are grouped into slow, fast and rapid charging points. 'Slow' points take 6-8 hours to fully charge an average electric car 'Fast' points take 3-4 hours 'Rapid' points take around 30 minutes to give an 80 per cent charge For up-to-date information regarding UK charging points see the Sources and related links section, below.

Are electrons the same as electric charge?
No. An electric charge is a property of certain particles (and larger amounts of matter); electrons have an electric charge of (-1) elementary units, but other particles also have electric charge. For example, protons have an electric charge of (-1), quarks may have charges like (2/3) and (-1/3), etc.
In which direction does the electric field point at a position directly north of a positive charge?
The electric field points directly away from a positive charge. Therefore, at a position directly north of a positive charge, the electric field would also point directly away from the positive charge.
What is true about an electric field around a negative charge?
The electric field around a negative charge points radially inward towards the charge. The field lines move from areas of higher potential to lower potential. The magnitude of the electric field decreases with distance from the negative charge.
What Electric potential or potential difference?
Electric potential (also known as voltage) is the amount of electric potential energy per unit of charge at a specific point in an electric field. It is measured in volts (V) and determines the ability of a charge to do work. Potential difference is the difference in electric potential between two points in an electric field and is responsible for the flow of electric current between those points.
In which direction does the electric field point at a position direcly south of a positive charge?
The electric field points away from a positive charge in all directions, meaning it would also point away to the south of the charge.
