We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
The generated voltage in a power station is AC voltage, not DC. So, it is never converted to AC, because it is already AC.
My husband said without hesitation AC!! DC power comes from batteries, AC power comes from electricity((generating power))....
There is no such thing as a d.c. transformer; all transformers work on a.c. So, what you are probably referring to is a power supply: the type of thing you would use, for example, to run a small radio or to charge a battery. In that case, no, you cannot plug a a.c. appliance into a power supply that has a d.c. output.

It is defined as dc power delivered to the load to the ac input power from secondary transformer
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
DC current is not used in home wiring. It may be used to power a door bell, alarm system, under counter lights, etc, that uses a transformer powered by AC that converts the power to DC. Other than that homes are wired for AC current only.
Let see an example. The active power absorbed by an AC motor is used to produce mechanical power delivered on the output shaft. If the mechanical power is negative (the motor is pushed to work as a brake) the active power 'absorbed' is also negative. The motor converts the mechanical power in active electrical power delivered in the electrical network. Any AC generator is supplied with negative active power, or it deliver to the network positive active power.
AC power, or alternating current power, is important in electrical systems because it allows for the efficient transmission of electricity over long distances. AC power can be easily converted to different voltage levels, making it versatile for various applications. Additionally, AC power is safer and more reliable than DC power for powering homes, businesses, and industries.
AC power, or alternating current power, works in electrical systems by constantly changing direction, flowing back and forth in a circuit. This flow of electricity is generated by power plants and transmitted through power lines to homes and businesses. AC power allows for efficient distribution of electricity over long distances and is used to power a wide range of devices and appliances.

An inverter changes DC power (like isgenerated from a solar panel) to AC to match the same type of power we get from the power company. A transformer reduces the power from a more powerful ACsource like a transmission lineto a lower AC source like the power to be used to be used in homes.
Both, in a way. Electronic components, including moth components inside the computer, need DC. However, since the power available in homes or offices is AC, a computer is designed to work with this. A computer has a power supply that internally converts AC to DC.
