DC can be generated by batteries, solar cells, fuel cells, thermocouples, commutator-type electrical generators, etc. An alternating current can be converted to direct current by using a rectifier. DC electric power is generally used in low-voltage applications. Most electronic circuits need a DC...
although it is often called “DC Current”. DCcurrentis defined as a unidirectional flow ofelectric charge. In DC current, the electrons move from an area of negative charge to an area of positive charge without changing direction. This is unlikealternating current(AC) circuits, where current ...
DC circuitshave a unidirectional flow of current and like AC it is not changing the direction periodically. Waveform of DC is a pure sine wave. As you can see, the voltage is constant with respect to time. DC Waveform Applications of DC: DC poweris widespread in low voltage applications su...
DC/DC converters are used in railway environments to convert DC battery voltages to a lower voltage for usage in a variety of control and energy circuits. This is because railway rolling stock uses a DC power distribution system so that batteries can be used to maintain electrical power in the...
Both AC and DC describe types of current flow in a circuit. Indirect current(DC), the electric charge (current) only flows in one direction. Electric charge inalternating current(AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because...
DC vs. AC Circuits Tutorial If you had a parallel RLC circuit, that is, an AC circuit with a resistor, inductor (L) and capacitor arranged in parallel with one another and in parallel with the power source, you would calculate current, voltage and resistance (or, in this case, impedance...
Alternating current may be less efficient for some electronic devices, as many electronic circuits require direct current and therefore need conversion, which can lead to energy losses. How is Alternating Current Generated? Alternating current is generated by alternating voltage sources, such as power ...
Switching regulator circuits have been around for many years and users have always had a choice between designing their own using discrete components or buying a finished... More > Podcast Building- & Home Automation / Energy / Industrial & Automation / Medical Medical-Grade AC/DC converters -...

DC circuits (left) versus AC circuits (right)Voltage - A Practical Example Electricity is very hard to imagine because we cannot physically see if the voltage is present or if a current is flowing, so we'll use a water analogy to try and explain how electrical circuits function. Water sy...
