Current Electricity NEET Questions with Answers: Download PDF

An electrical charge in motion is referred to as current or dynamic electricity. An electrical circuit is made up of a flow of negatively charged electrons from one atom to another through a conductor. It is referred to as electromotive force (emf) or voltage, and it is an external force that induces electron current flow of electric charge.

In the case of two bodies with different potentials connected by a wire, free electrons flow from Point 1 to Point 2 until both objects reach the same potential, at which point the current ceases to flow. Current flows through a conductor as long as there is a potential difference across the conductor.

Electrical Potential Definition: The electric potential created by an electrochemical cell or by changing the magnetic field is defined as the electric potential produced by altering the magnetic field.

Voltage Definition: The difference in electric potential between two places is known as the voltage difference.

There are two types of current electricity as follows:

• Direct Current (DC)
• Alternating Current (AC)

Direct Current: Straight-line current is the name given to electricity whose direction does not change. When electrons are constantly moving from a region of high electron density to a region of low electron density, this is referred to as direct current. In many household appliances and applications that need the usage of a battery, direct current (DC) is employed.

Alternate Current: Alternating current is a type of electricity that is bidirectional and constantly changes the direction in which the charge flow occurs. The bidirectionality is generated by a sinusoidally fluctuating current and voltage that alternates directions, causing the current to oscillate back and forth on a periodic basis. In our homes and businesses, alternating current is used to power the electrical outlets and equipment

The following methods can be used to produce current electricity:

When you move a metal wire through a magnetic field, you are creating electricity (Both alternating current and direct current can be generated by the following method)

By means of chemical processes initiated by a battery (Direct current can be generated through this method)

The term "static electricity" refers to the electric charges that accumulate on the surface of objects or substances. These charges stay static until they are grounded or released. This sort of energy is created as a result of fiction. Static electricity is a phenomenon that occurs when the charges of positive and negative charges are separated.
