Best Answer

Some devices operate on AC and others on DC. Generally, anything that uses mains electricity (120V US, 240V UK) is using AC electricity and things that use batteries or are rechargable like cell phones, ipods, personal CD, use DC electricity.

All gadgets containing electronics and silicon chips use DC .The AC is rectified and smoothed down to battery voltage levels by a transformer in the plug top adapter or circuit board within the gadget.

Cookers ,lights, power drills etc use AC.

Does a computer use AC or dc power?

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.


Can you use an AC Dimmer Switch on a DC fan?

No, an AC dimmer switch is designed to work with AC-powered devices, not DC. DC fans require a different type of dimmer switch specifically rated for DC power. Using an AC dimmer switch on a DC fan can potentially damage the fan or the switch itself.


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.


Can you use a ac fuse for dc?

No, it is not recommended to use an AC fuse for DC applications. AC fuses are designed to handle the characteristics of an alternating current flow, whereas DC fuses are designed specifically to handle the unique challenges posed by direct current. Using an AC fuse for DC applications can lead to safety hazards and may not provide the necessary protection for the circuit.


If ad is 10 units and ab is 8 units what is the measure of dc?

Given that AB = 8 units and AD = 10 units, we can use the ratios of corresponding sides in similar triangles to find the measure of DC. Since triangle ADC is similar to triangle ABC, the ratio of DC to AB is equal to the ratio of AD to AC. Thus, DC/8 = 10/AC. Solving for DC, DC = 8 * 10 / AC.

How can a radio use both DC and AC?

Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
