How a Seminar on Why can not you store AC power in battery like DC power?
WE can not change the AC power because AC power has two magnitudes one positive and the another one is negative.when we store the AC power in positive half cycle it store the energy and in the negative half cycles it discharge the energy so it is not possible for store the AC power like DC power
Can a 220 volts ac fan run in a 12 volts battery?
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
Will a compaq nc6000 run on ac power when the battery is dead?
A Compaq nc6000 will run on ac power when the battery is dead. The battery is long lasting but it can be charged by using ac power.
Is a battery consider AC power?
No. A battery is considered to be DC power.
Why can not you store AC power in battery like DC power?
Because ac is of changing polarity. It means the positive terminal becomes negative and vice versa... And this happens 60 times a second! So if we want store this, the terminals of the battery should be changed at the same speed as that of the supply which is not practicable ( and in theory it can be done by a electronic switch which constantly changes its polarity). So its better to convert this ac to dc, store it and then again to ac as in the case of a UPS.
Is recharging while using bad for the laptop battery?
No. When a laptop is plugged in, it immediately switches to AC power and begins charging the battery. The battery cannot become "overcharged" because special circuitry in the battery is designed to prevent this.
How do you make an inverter that stores the energy produced from a dynamo?
To store energy produced from a dynamo, you can incorporate a battery into the system. The dynamo generates electricity, which can be used to charge the battery. An inverter can then be connected to the battery to convert the stored DC energy into AC power for use when needed.
Battery ac or DC?
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.
What are the two power sources that power a laptop?
* Electric Power * battery
Why dc series motors cannot be used in 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.
Is battery ac powered?
No, batteries provide DC power.
What kinds of electronics use a DC power supply?
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
