The difference between zero line and fire line

Neutral (N) A neutral line, usually denoted by the letter "N", is a wire in an alternating current system whose main function is to provide a return path in the circuit. In a single-phase AC system, the neutral line is usually connected to the reference point of the power supply (usually ground) and

What is Primary Load?

What is Primary Load? Primary load definition Primary load refers to those loads that have very high demands on the power supply, and these loads may lead to serious consequences, such as life danger, significant economic losses, production stagnation, etc., if the power is cut off or the power is i

What is a Spike Current?

What is a Spike Current? Peak current definition Peak current refers to the short and strong current peak that suddenly appears at the moment of startup of some electrical equipment or under certain conditions. Peak current usually occurs at the moment when the device is just switched on, at which t

What is Diffusion Capacitance?

Diffusion capacitance definition Diffused capacitance is a kind of differential capacitance effect of p-n junction when it is positively biased. It is caused by the diffusion process of different types of materials in semiconductor devices such as PN junction or MOSFET, that is, a few carriers in th

What is Capacitive Load?

What are Capacitive Loads? Capacitive loads definite Capacitive loads are a special type of load in a circuit, used for absorbing and storing electrical energy. Compared with resistive loads, when receiving current, it will cause the voltage to lag and has a greater response to frequency. Capacitive

What is Diversity Factor?

What is Diversity Factor? Diversity Factor Definition Diversity factor is defined as the ratio of the sum of maximum demands of individual loads to the simultaneous maximum demand of the system. Importance of Diversity Factor A high diversity factor means that a smaller electrical source can serve m

Capacitance Definition

Another important property in AC electronic circuits, besides resistance and inductance, is capacitance. Capacitance is measured in units. The unit of capacitance is the farad. While inductance is represented in a circuit by a coil, capacitance is represented by a capacitor. In its most basic form,

Lenz's Law Explained

Lenz's Law, named after the Russian physicist Heinrich Lenz (1804-1865), is a fundamental principle in electromagnetism. It states that the direction of the induced electromotive force (emf) in a closed conducting loop always opposes the change in magnetic flux that caused it. This means that the in

What is Inductance?

What is Inductance? Inductance occurs when a change in current flow is exploited for the purpose of preventing signals with a higher frequency component from passing while allowing signals of lower frequency components to pass. This is why inductors are sometimes referred to as "chokes," since they
