In this article, we will see Star Delta Conversion and Delta Star Conversion. This conversion is widely used in the analysis of 3-phase electric power circuits. In simple words, it is used for the simplification of an electrical circuit in order to easily analyse the circuit. Star Delta Conversion In this section, we will see …Read more
The amount of charge flowing through any cross-section of a substance in a unit time is called Electric current. It can also be defined as the rate of flow of charge through any cross-section of a substance. If the electric current does not change with time, then electric current, i = q/t where q = …Read more
你可能已经通过了一项开路while solving electrical circuits. Lets see what is a open circuit in electrical circuits. When any element between two terminals is removed then it is called as open circuit between two terminals. The current in an open circuit is always zero regardless of the voltage across …Read more
You might have gone through the term short circuit while solving electrical circuits. Lets see what is a short circuit in electrical circuits. When any element between two terminals is replaced by a zero resistance path then it is called as short circuit between two terminals. The voltage across the short circuit is always zero …Read more
当两个或两个以上的电阻有限公司nnected end to end consecutively, they are said to be connected in series. Figure 1 shows four resistances R1, R2, R3 and R4 which are connected in series. Resistances in series is denoted pictorially as shown in figure 2. According to the law of combination of resistances in series, …Read more
Electric charge is a fundamental property of matter due to which electrical and other related effects are produced in the matter. The transfer of electrons from one object to another is responsible for the electric charging of the objects. Or Electric charge is the physical property of matter that causes it to experience a force …Read more
Electrical energy sources are majorly classified into two classes i.e. Independent sources and Dependent sources. The independent sources are further divided into two types namely voltage source and the current source. There are four types of the dependent sources. They are as follows 1. Voltage Controlled Voltage Source (VCVS) 2. Voltage Controlled Current Source (VCCS) 3. …Read more
Ohm’s Law Definition The current flowing through any conductor is directly proportional to the potential difference between two endpoints of the conductor at a constant temperature. where, ‘R’ is a constant known as the resistance of the conductor. The Ohm’s law can be applied to both AC and DC circuits. Limitations of Ohm’s law 1. It …Read more
In 1834, a French scientist Peltier discovered that if the junctions are at the same temperature and a current is passed through the circuit of the Thermocouple, heat is produced at one Junction and absorbed at the other i.e. one junction (former) is heated and the other junction (later) is cooled. This is known as Peltier …Read more
Active Power The actual amount of power being used, or dissipated, in a circuit is called True power or Active Power or real power. It is measured in watt (W) or kilowatt (kW) or MW. It is symbolized by the capital letter P. It has been seen that the power is consumed only in resistance. Reactive …Read more
