This circular path, which is always required to get electricity to flow and do something useful, is called a circuit.A circuit is a path that starts and stops at the same place, which is exactly what we're doing. Click this linkto see a simulation of current flowing through a simple cir...
Voltage is measured in volts (V). Like current, voltage is also related to the flow of electrons in a circuit. Current refers to the flow of electrons, while voltage refers to the amount of force pushing the flowing electrons. The higher the voltage, the more current will flow; a lower...
Can I change the parameters of a virtual circuit after it has been established? Yes, it is possible to modify the parameters of a virtual circuit after it has been established. For example, you can adjust the allocated bandwidth, modify quality of service settings, or change security configurat...

Alternating Current (AC) vs Direct Current (DC) What Is a Short Circuit? What is Negative Voltage? The RC Delay Element Tips: How to combine components? Tips: An expert in electronics does easier tasks Tips: This trick will help you understand circuits ...
Today I would like to share with you the working principle of a DC-to-DC Buck converter, or as some people may know it, a step-down DC-to-DC converter circuit. Since it is highly effective and cheap, it is very popular nowadaysf. ...
Low ripple current DC-DC converter with 75 µH Inductor Figure 2 Real inductors have turn-to-turn winding capacitance that acts as if it were a parallel circuit element. The self-resonant frequency (SRF) of an inductor is the frequency at which the inductive reactance is equal in magnitude...
A 12V AC to DC converter is an electronic device that changes the voltage of an alternating current power source to a direct current power source. This converter is specifically designed for LED lights, which require a constant DC voltage to function properly. Why do we need a 12V AC to DC...
What Is a Circuit? The answer to this paradox is found in the concept of acircuit: a never-ending looped pathway for charge carriers. If we take a wire, or many wires, joined end-to-end, and loop it around so that it forms a continuous pathway, we have the means to support a uni...
The equivalent circuit of a DC source is the generated emfEg, in series with internal resistanceRi, of the source as shown in the figure. Load CurrentI=Eg/ (RL+Ri) Terminal VoltageV=Eg–IRiorIRL Alternating Voltage Source A device which produces alternating voltage output continuously is know...
