variable dc supply are used to get desired amount of dc supply
Batteries can provide both AC (alternating current) or DC (direct current) power, depending on the type of device they are connected to. However, most batteries themselves supply DC power. Devices that require AC power typically use an inverter to convert the battery's DC power into AC power.
No, the 1A power supply does not provide enough current (3200mA required) for the device to operate properly. You need a power supply that can deliver at least 3200mA to meet the device's power requirements. Using an underpowered supply may result in the device not functioning correctly or potential damage.
In a wall adapter there is a device that converts AC to DC. Inside the adapter there is usually a transformer that reduces the voltage down to a working voltage of the equipment that the adapter plugs into. The output of the transformer is then connected to either a half wave or full wave bridge rectifier. More expensive adapters will have a resistive capacitive network in them to smooth out the ripple DC that is supplied on the output of the bridge rectifier.
A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
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.
Variable dc supply is applicable in loads that are variable.
Variable DC power supply is: Variable - you can adjust it DC - direct current, electrons (electricity) flows in only one direction power supply - power supply Together, it's an adjustable one-way power supply Hope you find this useful...
You can purchase a variable DC power supply online from retailers such as Amazon. Once on the website, type "Variable D/C Power Supply" into the search field at the top of the page and press enter to bring up the items.
DC Power is Direct Current Power Supply.
conclusion of dc power supply 9V
In an ideal DC power supply, there is no ripple.
dc power supply
DC 12V power supply can convert 110/220V AC power source to 12V DC.
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
The DC supply may supply power to trip breakers, or to power the protective relays.
You could try using a simple variac to make the power supply from 220 V AC to 300 V DC variable adjustable. This will work just fine if you don't have a workable circuit.
