AC is easier and cheaper to send from the generators to the consumers than DC is.
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
Yes, it has electronic components inside that are powered by electricity (either mains AC and or battery DC).
As far as I know, transistors - and other electronic devices - basically work with DC, not AC. If a computer (for example) is plugged into an AC outlet, some device within the computer must first convert the AC current into DC current, which is then fed to the electronic components.
An AC drive is a device use for control AC motor speed, also knows as variable frequency drive, a reactor in an AC circuit is basically an inductor which will filter spikes in source voltage.and AC chokes are typically used as the inductive components in electronic filters. - roxas_riku
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.
Yes, the theorem still applies for AC.
For some equipment it doesn't matter, other types of equipment will be destroyed. For a simple electric heater or an incandescent bulb AC or DC are acceptable, provided the rms voltage of the AC is equal to the DC voltage. If the heater has a time switch, DC is unacceptable. A DC motor may or may not work with AC depending on its type and size. The commutator motor as used in vacuum cleaners is essentially a DC motor, but most types of AC motor are not interchangeable to DC. Electronic circuits usually required a DC supply and if AC is applied many of the components will be destroyed.
It allows you to use mains power instead of batteries
an adapter can help in this case.
A neutral line can carry both AC and DC. Just make sure that the AC or DC is unable to pass through any components connected to the neutral line.
Obviously you have not yet begun the AC circuit analysis class. Wait a few quarters.Some components are normally used with DC, some components are normally used with AC, but most components can be used with both DC and AC.
we generally use filters to smooth the sharp curves of DC component we get when we rectify AC components the pulsating Dc is not desirable to a no. of devices. These filters are used to make the pulsating DC to a stable one . To be more clear a pulsating DC is viewed as a sum of DC component and AC component these filters actually block the AC components and retain the DC component . so, mainly capacitors and inductors are used to obstruct or pass the dc components respectively
