Why do we need DC power supply for electronic devices?
Most active electronic devices (devices that amplify or switch states, e.g. vacuum tubes, transistors) only operate when conducting in one direction. If the current reversed periodically (as it does in AC) these devices would either not work at those times or would do something much different than they were designed to do. Thus DC is needed to keep them operating all the time.
What is the difference between electrical devices and electronic devices?
Electronic devices works on low level dc voltage like 48volts and less than that. We cannot give direct line supply to electronic devices, for this transformer is used to convert ac voltage to required dc level... Whereas in electric devices we can use direct line supply (110V/220V) ac. These devices can also be operates on dc volts but greater than 48volts
What devices typically use DC current to operate?
cell phones, laptops, desktops, anything that uses a battery. most power supplies convert AC to DC at a regulated voltage and current.
Converters is a device used to transforming. AC to AC Dc to DC DC to AC AC to DC?
Converters are electronic devices used to transform electrical power from one form to another. They are commonly used to convert AC (alternating current) to AC, DC (direct current) to DC, DC to AC, and AC to DC. Here's a breakdown of each type of converter: AC to AC Converter: AC to AC converters, also known as AC power controllers or AC voltage controllers, are used to control and modify the amplitude, frequency, or phase angle of an AC voltage waveform. They are often employed in applications such as motor speed control, lighting dimmers, and power regulation. DC to DC Converter: DC to DC converters, also called DC-DC converters or voltage regulators, are used to convert one DC voltage level to another. They operate by converting the input DC voltage to a high-frequency AC waveform, which is then rectified and filtered back to a DC voltage at the desired output level. DC to DC converters are commonly used in power supplies for electronic devices, battery charging systems, and renewable energy systems. DC to AC Converter: DC to AC converters, also known as inverters, are devices that convert a DC power source (such as a battery or solar panel) into AC power. They generate a high-frequency AC waveform by using switching techniques, and then the AC waveform is typically filtered and regulated to provide a stable AC output. DC to AC converters are widely used in applications such as solar power systems, uninterruptible power supplies (UPS), and electric vehicle inverters. AC to DC Converter: AC to DC converters, also referred to as rectifiers, are used to convert AC power into DC power. They typically employ diodes or other semiconductor devices to rectify the AC waveform, resulting in a pulsating DC waveform. Additional filtering and regulation stages are often employed to provide a smoother and more stable DC output. AC to DC converters are commonly found in power supplies for electronic devices, battery chargers, and many household appliances. The selection of the appropriate converter depends on the specific application and the desired conversion requirements. Converters play a crucial role in enabling the use and compatibility of different types of electrical devices and power sources.

What is the Difference between frequency converter and frequency inverter?
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

What happens if the positive DC voltage is replaced with a negative DC source?
A negative DC source could be connected in such a way as to act as a positive DC source. I'm not sure why you would want to flip it - supplying power "the wrong way" could cause equipment failures, protective systems (such as fusing) to not provide protection, and general other bad things.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
How do you conver ac power into pulsating DC What devices you need?
rectifier circuit convert ac to dc signal
Why you use dc supply in generator protection panel?
The DC supply may supply power to trip breakers, or to power the protective relays.
What are the devices that make used of electromagnet?
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.
