There are several ways. the most simplest is by using a single rectifying diode that only lets current pass in one direction. This is called a half wave rectifying circuit. You only get half the power also.
The second is by a full wave, or bridge rectifier which consists of 4 rectifying diodes which can usually be bought as a single package with 4 pins which are identified for correct connection. This allows the alternating cycle current to pass alternatively to the output pins in a push-push mode and maintains most of the current flow that you put into it.
The result is a very jerky or spikey DC current usually higher than the rated AC voltage. To smooth the spikes, extra circuitry is needed such as capacitors and maybe some smoothing coils but is way too detailed and varied for printing here.
Type in your browser "Rectifier Circuits" and you will find a smorgasborg of results where some will give a more comprehensive explanation of how AC is converted to DC.

Why are you asking someone to do your homework for you? Ask your teacher.
from the wall it could be 115v ac, or in non American countries that use it 230v ac. internal voltages range from 12v dc, 5v dc, 3.3v dc.
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
Turn the DC generator inside out and you have an alternator .
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
You will need a regulator circuit that will change the shape of the pulse AND regulate the voltage to 5v.
you need a DAC, not just a buffer.
Simple use a 2.25 ohm 25watt ballast resistor;renault used them to drop the voltage for the Engine control computers.
By changing the polarity of the source
By changing the polarity of the source
12v dc to 3v dc
7K ohm
5V dc motor is the best for the robotics materials and it is inexpensive as compared to the other motors. dc motor is made up of the magnetic coils consist north and south pole
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
12V, 5V
One invert the function or a signal. the other is a pulse width modulator controller which are usually used to convert one source of power to another. As in 12v dc in 5v dc out or vice versa
