Q:The function of computer monitor power adapter
Third is OUTPUT (output), voltage * current = power, it can calculate the number of watts
Q:What is inductance effect
The ratio of the change of the magnetic flux to the amount of the change of the current is called self inductance
Q:Main parameters of inductor
Inductance, also known as self inductance, is a physical quantity that represents the inductance of the inductor.
Q:What are the two functions of the inductor in the circuit
The inductor current change process does not hinder the consumption of electric energy
Q:What is the role of inductance in the power supply
The effect of inductance is to prevent the change of electric current
Q:Is the inductor inductor
Divided into inductive and capacitive reactance, classification and comparison of science is impedor (inductors) and capacitive devices (capacitor) referred to as the reactor, but because of the past with the first inductor, and is called the reactor, so the capacitor is now known as capacitive device, and reactor as an inductor.
Q:Laptop power adapter is used to do
the production of 1.8V, 3.3V, 5V and many other groups, such as CPU voltage for the memory component operation
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
Q:Inductance and capacitance how to understand?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H), named after the American scientist Joseph Henry.
Q:Laptop power adapter are AC-DC dual-use
General notebook power adapter are DC output, AC DC converter.
Our products have perfect protection functions, which includes complete over-charge, over-release, over temperature, over-current and over-voltage and have stable, safe and reliable performance.
