A CPU works off of DC voltage. If you monitor the current draw of a CPU, it will likely not be DC, since a modern CPU is a CMOS design, current is only drawn when transistors are switched (ignoring the small leakage current). This is why overclocking (forcing the transistors to switch faster) can cause the CPU to overheat, and why "power save" mode on a laptop sometimes slows down the processor speed.

Battery ac or DC?
A battery supplies DC.
What is true regarding DC current?
A DC current flows only in one direction.
How does an 120VAC LED light bulb work?
LED's (Light Emitting Diodes) work on DC current, not AC, so the AC needs to be stepped down to an appropriate voltage via a transformer (probably only a few volts), converted to DC via a rectifier and filter (to smooth out the ripple current). there are a constant driver in side the 120V AC led light bulb , this driver transfer the AC to DC, so the led could work with DC.
Why does a 36 volt dc motor only run on 12 volts?
Motors work on both DC and AC. It depends on their design.
Does dc current have hertz?
No.
Will a photocell work using dc voltage?
it creates a dc current
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
How does a power inverter work?
Power inverters work as an electrical converter which allows a direct current to change into alternating current. This is the commonly known as a DC-AC power conversion. In short, inverters work the opposite as rectifiers that converts AC or alternating current into DC or direct current.
If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?
first, understand that a transformer is an AC DEVICE. it wont work on dc...
Does watt meter use for ac and dc?
No, on dc the power is measured by the produce of the voltage and current so there is no need for a wattmeter, which would not work on dc anyway.
How DC generator produces DC current from ac current?
DC GERATORS PRODUCE DC current with the help of spilt ring commutators.
DC current is not used in transformer?
No. Transformers rely on the magnetic field changing direction to work, so DC can't be used.
What objects work with dc current?
Things that need a battery in order to work, must need Direct Current at some point, if not all, for it to work. eg a hand torch.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Battery ac or DC?
A battery supplies DC.
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
Is electronics device only work in direct current?
Electronics devices are work both AC and DC currnt . Such as Diode , SCR , Capacitor can work both AC and DC current . Espacilly voltage control circuits such as dimmer , and then voltage rectifier circuits , means power suppy circuts and so on.
