What Is A Voltage In Science

Static electricity is the build up of electrons on an insulator.

What is a voltage in science. There is a basic equation in electrical engineering that states how the three terms relate. The electrical energy can be converted into other types of energy such as light heat movement or sound. Faulty wiring in your house or apartment building. Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge electricity is related to magnetism both being part of the phenomenon of electromagnetism as described by maxwell s equations various common phenomena are related to electricity including lightning static electricity electric heating electric discharges.

It says that the current is equal to the voltage divided by the resistance or i v r. In other words it is a measurement of the energy contained within an electric field or an electric circuit at a given point it is equal to the work that would have to be done per unit charge. This is known as ohm s law. An electric current is the flow of electrons around a circuit.

We make electricity by creating an electric circuit. Problems with the equipment of your utility company. If a unit of electrical charge were placed in a location the voltage indicates the potential energy of it at that point. Electricity is the presence or flow of charged particles.

Or when equipment that draws a lot of electricity. Consider the floor of your room to be ground level and set an object such as a ball on the floor. Let s take the case where you are turning on a light in your house. Voltage is a measure of potential energy the amount of energy stored in an object.

The term recognizes italian physicist alessandro volta 1745 1827 inventor of the voltaic pile the forerunner of today s household battery. Voltage is a representation of the electric potential energy per unit charge. Let s try to understand this by illustrating potential energy using a more familiar context. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size.

Power surges which increase the voltage in your electricity lines can be caused by lightning striking nearby increasing the electric pressure by millions of volts even a surge protector won t be able to save your computer in this case. Voltage is the pressure from an electrical circuit s power source that pushes charged electrons current through a conducting loop enabling them to do work such as illuminating a light. When you flip the switch on you are completing the electric circuit and causing electricity and electrons to flow through the light bulb turning the light on. The greater the voltage the greater the flow of electrical current that is the quantity of charge carriers that pass a fixed point per unit of time through a conducting or semiconducting medium for a given resistance to the flow.
