The purpose of separating ground, live and neutral wires in a circuitFire lineTransmission of electrical energy: The fireline is the main line responsible for the transmission of electrical energy in the circuit. It transmits the alternating current provided by the power supply (such as 220V mains) to various electrical equipment to provide the energy required for the electrical equipment to work. For example, when you turn on a light bulb, the current flows from the live wire into the bulb, pas

The skin effect refers to the phenomenon where, under the influence of an alternating electric field, current tends to concentrate near the surface of a conductor. As frequency increases, this effect becomes more pronounced. In high-frequency power transmission systems, the skin effect can significantly impact the design. Here are the specific influences and corresponding design considerations:Conductor Size and Shape Conductor Diameter: The skin effect causes the current to primarily concentrat

If the positive and negative terminals of an electrolytic capacitor are connected in reverse, i.e., reverse-biased, it can lead to a series of problems and potentially damage the capacitor. Electrolytic capacitors are polarized capacitors that contain an electrolyte. The positive terminal is typically a metal foil or a metal foil coated with an oxide layer, while the negative terminal is usually made of metal powder or carbon. The electrolyte serves to isolate the positive and negative terminals

When assessing the dangers associated with electricity, voltage, current, resistance, and frequency are all important factors, but their significance depends on the specific context. Understanding the role of each parameter in electrical hazards can help better comprehend potential risks. Below is a discussion of the importance of these factors:Voltage (Voltage) Definition: Voltage is the force that drives current through a circuit. Importance: Higher voltage means there is more energy available

Connecting two polarized capacitors (typically electrolytic capacitors) together requires careful attention to their polarity to ensure they operate correctly and avoid damage. Polarized capacitors have distinct positive and negative terminals, and incorrect connections can lead to damage or even explosions. Here are some guidelines on how to properly connect polarized capacitors:Parallel Connection (Parallel Connection)If you want to connect two polarized capacitors in parallel to increase the

Capacitors of different voltage levels can be used in parallel under certain conditions, but some key factors need to be noted to ensure safe and efficient operation. Here are some details about parallel capacitors with different voltage levels:Parallel possibility Voltage matching: First, the rated voltage of the capacitor should be lower than or equal to the rated voltage of the circuit, especially the direct current container. If the voltage difference is too large, it may cause the capacitor

How to convert single-phase electricity to three-phase electricityTo convert single-phase electricity to three-phase electricity, a frequency converter is usually used to achieve this. The inverter uses electronic devices (such as MOSFET tubes, IGBT, etc.) to achieve the conversion between DC and AC, and outputs different phases or frequencies according to needs to achieve single-phase and three-phase conversion, the process is as follows: Rectifier: The single-phase power supply is first rectif

The number of electrons per second flowing through a wire in a circuit can be calculated from a known current value. Current is measured in amperes (Ampere, A), defined as 1 Coulomb (C) of charge flowing through a cross section of a wire per second. We know that the charge of 1 coulomb is equal to about 6.242 x 10^18 electrons.Calculation formula Current (I) : Current is measured in amperes (A) and represents the amount of charge passing through a cross section of a wire per unit time. Number of

Causes of inability to transmit power using direct current (DC)There are some key differences between direct current (DC) and alternating current (AC) in power transmission, and these differences make DC not suitable for power transmission in some cases. Here are a few main reasons: Lack of voltage conversion capability: Transformers are the core components of alternating current systems, which allow power to be converted between different voltage levels. Because the current direction of direct

The reaction of the capacitor when the inductor leads the voltageWhen the rate of voltage change on the inductor is higher than the rate of current change, the inductor is inductive, and the voltage is ahead of the current. Under such conditions, we discuss the reaction of the capacitor.The phase relationship between voltage and currentIn circuitry, the phase relationship between voltage and current refers to the time difference and Angle difference between them. In an AC circuit, the phase rela
