simple capacitor can do this job (to block dc and pass ac).
In electronic circuits a capacitor is used to pass AC and block DC.
AC coupling is where a capacitor is used to block the DC componant of a signal. Used often in Medical devices when a DC componant could harm a patient Coupling refers to transferring electrons trough a media. It could magnetic such as coils proximity. A transformer and yes even a capacitor. And no it has no medical devices ONLY application.
rectifier circuit convert ac to dc signal
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
High pass filters are used in circuits such as microphones to block out DC signals and pass the AC. In a microphone, DC power is used to power the microphone but should not appear on the output with the audio signal. Only the AC should appear on output which represents the voice signal, music, etc. To block out DC and pass AC, a high pass filter is used.
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
A choke coil is used in several electrical devices. The function it has is to block AC currents from passing through as it allows DC currents to pass through.
In electronic circuits a capacitor is used to pass AC and block DC.
Block DC components and pass AC component
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.
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

can you block the high side on the ac on a car to stop a leak
Inductors are low pass devices, they conduct most easily at low frequencies. DC is the limiting case for low frequency AC: i.e. DC is the lowest possible AC frequency, zero Hz and thus conducts best through an inductor. Capacitors are high pass devices, they conduct most easily at high frequencies. Infinite frequency AC is the limiting case for high frequency AC. Infinity Hz would conduct best through a capacitor.
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.
