Doc Al said:The potential at a distance "r" from a point charge of Q is given by:
[tex]V = \frac{kQ}{r}[/tex]
The minus sign is incorrect. The potential increases as you get closer to a positive charge. (The zero potential is taken to be at r = ∞.)jatin9_99 said:V= -kQ/r i just added a negative sign to it to make it more sophesticated
A charge electrical point is a location where an electrical charge is present. It can be either a positive or negative charge and is typically measured in units of Coulombs.
Charge electrical points are created through the transfer of electrons between objects. This can happen through friction, contact, or induction.
Positive charges have an excess of protons, while negative charges have an excess of electrons. These charges attract or repel each other depending on their polarity.
Yes, charge electrical points can be controlled through the use of conductors and insulators. Conductors allow charges to flow freely, while insulators prevent the flow of charges.
Charge electrical points are used in a wide range of technologies, including batteries, capacitors, and electronic circuits. They are also essential for the function of everyday devices such as cell phones, computers, and household appliances.
