Aside from the difference in flow direction, another main difference between the two is that AC power can be easily adjusted, or throttled, via transformers. By throttling the power up (e.g., into the hundreds of thousands of volts), power can be moved at a lower current — which directl...
Can be easily converted to different voltage levels using transformers Widely used for powering various appliances and electrical devices Majority of electrical grids and power systems are designed for AC power Cons More complex than DC power Possibility of electromagnetic interferences Potential safety haza...

Basics Technical Explanation of AC Power - AC Power Supply: Fundamentals and International Differences, single-phase and Three-phase electric power connection, Types of programmable AC power supplies.
The Basics – Wires or Cables Whether it’s a 600v DC cable that you are looking for, or a 12V AC power cord that you need for an electronic device – the question many non-engineers ask is: What type of wire do I need? Well, most technical-minded individuals would frown at the ...

Power factor correction, to control power factor by adding reactive elements of specific impedance.It's precisely calculated. Week 5 This week is about transformers.Really, they're just everywhere.It changes VI to V'I', that's it. The basic structure and idea are simple: two coils, wrapped...
Transmission of Electrical Power Transmission Rectification The conversion of alternating current (AC) to direct current (DC) This involves a device that only allows one-way flow of electrons semiconductor diode Half-wave Rectification allows one half of an AC waveform to pass through to the load ...
usually used to transmit energy over long distances, as the high voltage keeps energy loss low. So-called transformers make it possible to convert high voltage into low voltage (which is safer and more applicable). However, transformers only work with alternating current, not with direct current...
Reactive power is stored in and discharged by inductive motors, transformers, solenoids and capacitors. A pure inductor and a pure capacitor do not consume any power since in a half cycle whatever power is received from the source by these components, the same power is returned to the source....
