is the process of converting AC to DC.

an electronic device that allows current flow in only one direction

is required to ensure that electrons flow from x-ray tube cathode to anode only

an ekectronic device that contains two electrodes

originally, all diode rectifiers were vacuum tubes called _

lies between the range of insulators and conductors in the ability to conduct electricity

two types of semiconductors

have loosely bound electrons that are relatively free to move

have spaces called holes, where there are no electrons

rectifiers are located in the

is a condition in which the voltage is not allowed to swing negatively during the negative half of its cycle

x-ray tube serves as the vacuum tube rectifier

circuit that rectifies the entire AC waveform

the exposure time for any given technique is cut in half

results in pulsating beam. this caused by the alternating swing in voltage from zero to maximum potential 120 times each second under full wave rectification

multiple voltage waveforms are superimposed on one another, resulting in a waveform that maintainsna nearly constant high voltage
