The work done in moving the electric charge from one point to the other point in the electric field is called a potential difference between those points. The horoscope is also a voltage and it is also a scalar.
The capacitance of a driver (c) is the result of the charge (q) given to the conductor and the result of the change in the driver’s potential (v). To wit –
C = q / v is the number of SI is Faraday (F).
Electric current: The flow rate of the electric charge in a conductor is called electric current. The direction of flow of the positive charge is considered as the direction of the current.
Electric cell: Chemical energy is converted into electrical energy in the electric cell. Cells are of two types – primary and secondary.
Electrical carrier force of cell: 1 coolm charge to carry out a full cycle in the whole electric circuit, the work done by cell for cell or V.V. it is said. V.V.V. is the quantum voltage.
Probable: When the stream flows through the cell, then the potential difference between the ends of the cell is called the potential of the cell. It is less than V.V.
Internal resistance to cell: Resistance in the path of electric current by the electrolysis of the cell is called internal resistance to the cell.
Thunderbolt: The lightning conductor is between two charged clouds or between charged clouds and earth. The lightning conductor is a pearl copper band, at which many pointers are formed at the top end. This pointy tip is placed at the top of the buildings and the other end is buried in the ground with a copper strip. When the charged clouds pass over the building, their charge is taken by the driver and it is transferred without any charges to the land. Thus, it is used for the protection of buildings.
Hans Christian Orsted (1777-1851)
One of the leading scientists of the 19th century, Hans Christian. Orsted played a decisive role in understanding electrical magnetism. In 1820 AD, he accidentally discovered that there was a distortion in Dikuchi, near the passage of the flow of electric current in a metal wire. On the basis of their observations, Ostend has certified that electricity and magnetism are interrelated phenomena. His research went ahead and developed new technologies; Such as radio, television, fiber optics, etc. In the respect of her, the magnitude of the intensity of the magnetic field is kept, orsted.
rules of OM
The value of an electric current flowing in a conductor is in proportionality of the probability associated with its end. Therefore
Where V probability, I stream and R for that driver is a determinant in those circumstances, which is called the electrical resistance of the driver. Therefore, in the voltage and the current in the amplifier, the value of the resistance will be in the voltage / ampere. Volt / ampere is called ohm.
Those drivers who follow the rule of Om, they are called osmotic resistance, and their resistance is called omega-resistance, such as manganese wire.
Those drivers who do not follow Ohm’s rule, are called anomalous resistance and their resistance is called anomalous resistance, such as resistance to the triode valve.
The electrostatic resistance between the face panels of one meter side of the money for a driver’s substance is known as the specific resistance of that substance. It has an ohm meter. Resistance on thick wire made of the same substance is less and resistance to thin wire is more, but the specific resistance of both is the same, because it only depends on the nature of the substance.
Hierarchy adjustment of resistors
If the resistors are added to each other so that the same stream flows in them and there are different possible differences between different resistors. So this is called the adjustment in the range of resistors.
Parallel sequence adjustment of resistors
If the resistors should be added in such a way that there is a lot of possible accessories on each resistance, but the currents can remain uneven, then it is called the parallel sequence of resistance.
Effect of heating on resistance
The resistance of pure metal wire increases with heat. Therefore, resistance to R = R0 can be calculated on any heat. Where a metal has a heat resistance coefficient and R0 is the resistance to that metal 0 ° C.
The rate of energy decay in power circuit is called power. It has an SI number watt. Power can be expressed as a formula in this way –
Power = section x probability
And 1 by = 1 ampear x 1 bolt
