Ac to DC formula?
formula for ac to dc
Which choice defines AC and DC correctly?
Choice of electricity defines ac and dc
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
Advantages and disadvantages of dc shunt motor load?
Advantages·Installations of DC machines are found more regularly within heavy industrial practises, as torque and speed can be varied over a wide range easily, and with minimal reductions in efficiency.·DC motors are often favoured in industry, as post installation, power supply is cheap and simple to maintain, and can also be utilised straight from a battery unlike AC supplies·The speed of a DC motor can also be controlled with a simple and inexpensive control unit compared to that of an AC motor, as only the armature voltage control is needed.Disadvantages·DC machine installations are expensive. They also require large and potentially damaging currents upon start-up before power efficient speeds can be achieved.·Despite the advantages stated above, DC machines are seldom used as a form of power supply within industrial premises; as power is supplied as AC by default, and cost of installation is too high.·DC motors are unreliable at low speeds, and are also physically much larger than AC supply motors.·DC machines use commutators that reverse current. These are susceptible to wear and tear unlike slip rings that are used in AC machines instead, therefore resulting in higher maintenance expenditure.
Which current is better ac or dc?
DC is more powerful, the actual ratio is 1.732AC=DC
What were the advantages and disadvantages of DC component?
what is meant by dc components???
What are the advantages of DC to ac inverter?
Dc invereters are not well suited as compared to ac inverters.This is due to the reason because ac inverters are more efficient ,less dangerous and good for supply over distance.
What are the advantages and disadvantages of moving coil galvanometer?
Advantages: High sensitivity and accuracy. Can measure both AC and DC currents. Low power consumption. Disadvantages: Limited range of measurement. Susceptible to external magnetic fields. Requires frequent calibration.
What are the advantages of DC over AC in extraction of copper?
DC is necessary in the electrolytic process to refine copper. In other processes for extracting the metal from the ore, where heat is needed, AC is preferred because it is more easily transmitted over distances.
Advantages of Ac to DC converter?
some things requre a dc (direct current) rather than an ac (alternating current)
What is the advantages of the universal motors?
the universel motor can runs at both ac and dc supply.
What are the advantages of using a DC motor over an AC motor for garage door openers?
Usually a DC motor can be expected to deliver higher torque in a smaller size package.
What are the main advantages of using a DC To AC Converter?
The major advantages of using a DC to AC converter are that it can reduce electrical consumption. Similarly, these converters can charge many important items, such as phones and laptops.
How do you change over a ac motor to a dc generator?
Type your answer here... how can you change an ac motor to a dc generator
Which is more useful ac aor dc?
AC and DC current both have useful advantages, depending on what you what to do with it.AC is more useful for sending long distance over transmission lines, as AC can be put through a transformer to change the voltage easily.All electronic devices work using DC only. Batteries provide DC and are readily available or can be created. All electronic devices, when used on a domestic AC supply, have their power converted from AC to DC, either within the device or an external power supply.More devices use DC than AC, but we could not get the power to where it is needed without AC transmission lines. Heavy motors were more efficient when constructed for AC supplies, but these days DC stepper motors are taking over, using electronic control circuits.
What are the advantages of using a DC motor in a ceiling fan compared to a traditional AC motor?
DC motors in ceiling fans offer advantages such as energy efficiency, quieter operation, and variable speed control compared to traditional AC motors.
