direct current.
dc stands for direct current. This can be obtained from a battery or a rectified ac (alternating current ) supply.
Yes. Alternators supply alternating current.
A notebook computer generally requires direct current. This current comes from a battery or a power supply. A battery converts chemicals into electricity, while a power supply or battery charger converts somewhat high voltage alternating current into lower voltage direct current.
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains 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.
Mains supply provides alternative current while battery provides direct current.
Yes, it is true that current supply from generating plants is an alternating current. There is no success found in bulk power generation of direct current ( D.C. ) in a power plant. But yes it is possible to transmit the power in the form of direct current ( High Voltage Direct Current Transmission-HVDC Transmission ) that possible after converting the generated alternating current into direct current with the help of high range converters.
UPS (UNINTERUPTED POWER SUPPLY ) Its charg only AC current (Alternating current). and inverter provide current DC TO AC ( Direct current to Alternating current)
An 'inverter' takes direct current (DC) input from a battery and outputs alternating current (AC). This means that an electric drill that should be plugged into the mains, can be run from the inverter.
Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.
Why direct current (DC) can be stored but alternating current(AC) can not be? Current means flow of charge per unit second. Any flow cannot be made stationary. Then it is not flow. Hence both direct current and alternating current cannot be stored. We can store only charges. In capacitors we store charges and not current. For storing we use direct supply or direct voltage When a capacitor is connected to a battery, which is a source of direct voltage, each plate of the condenser get charged. Charges remain in the plates. No current flows in between the plates. When the source is removed, there are some charges left in the plates. We say that charges are stored in the plates. If an alternating source of supply is connected in between the plates,every instant ,the charges in the plates are alternating and they are not stationary. When ac supply is removed, all the charges move out of the plates and hence no charge is left in them. Hence charges can be stored with dc supply and not with ac supply. However as long as the ac is connected to the capacitor, the capacitor gets stored and emptied with the frequency of the ac supply.
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
