what is the difference between static and current electricity for class 7?
69615
Difference Between Static & Current Electricity. The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.

Constant is just a constant, i.e. you can't change its value after declaring. Static variable is accessible without making an instance of a class and therefore shared between all the instances of a class.

When two electrically charged objects, such as the human body and an electronic device come into contact with each other, static electricity is discharged. ... This high voltage pulse enters the electronic device that is touched, resulting in a malfunction or destruction of the IC circuits inside it.

The load circuit receives (so to speak) power from the phase conductor, and returns (so to speak) power back to the neutral conductor. ... The only difference between phase and neutral is that neutral is grounded at the distribution panel. This is a single point ground so, technically, no current flows on ground.

Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

There are two types of Electricity, Static Electricity and Current Electricity. Static Electricity is made by rubbing together two or more objects and making friction while Current electricity is the flow of electric charge across an electrical field.

The major difference between electricity and magnetism is the presence of magnetism. Electricity can be present in a static charge, while magnetism's presence is only felt when there are moving charges as a result of electricity.

For both static and current the subatomic particle responsible for creating electrical charge are electrons because protons can't move and neutrons have no charge.

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

Three basic types of loads exist in circuits: capacitive loads, inductive loads and resistive loads. These differ in how they consume power in an alternating current (AC) setup. Capacitive, inductive and resistive load types correspond loosely to lighting, mechanical and heating loads.

Voltage is दबाव. Current is बहाव. Power/watts is प्रभाव.

Electrical Charge Electricity is the movement of electrons. ... Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. Most students of electrical engineering and related subjects begin their studies by learning about direct current (DC).

Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. ... Alternating current (AC) is the flow of electric charge that periodically reverses direction.

Voltage lags current by 90° in a pure capacitive circuit. In a pure capacitive circuit, the instantaneous power may be positive or negative. As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative.

Current lags voltage by 90° in a pure inductive circuit. In a pure inductive circuit, instantaneous power may be positive or negative.

AC stands for 'alternating current' which means the current constantly changes direction. Mains electricity is an AC supply, and the UK mains supply is about 230 volts. It has a frequency of 50Hz (50 hertz), which means it changes direction and back again 50 times a second.
