A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, Mercury-arc valves, solid-state diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motors have been used. Early radio receivers, called crystal radios, used a "cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detector".
Rectifiers have many uses, but are often found serving as components of DC power supplies and high-voltage direct current power transmission systems. Rectification may serve in roles other than to generate direct current for use as a source of power. As noted, detectors of radio signals serve as rectifiers. In gas heating systems flame rectification is used to detect presence of flame.

What kind of moon phase is after the last quarter?
New moon.
Wiring 240 volt electric motor?
Phase to Phase, Neutral to Neutral, Earth to Earth. If its a new motor it should have the wiring for a capacitor and centrifugal switch done internally. Otherwise run a wire from the phase, through the centrifugal switch, into capacitor, into start winding, and back to neutral. So many different kind of single phase 240v motors though, cap start, cap start cap run etc all involving different wiring

What kind of motor is used either on ac or dc supplies?
single phase induction motor
What kind of electrical savings can be expected between a 3 phase convection oven and a single phase?
Virtually nothing. The only real benefit you would get is if you had three phase vs. single phase fans, and I'm fairly certain even the three phase convection ovens use single phase fans. The oven will be rated at a certain kW usage, which applies whether it's three phase or single phase (...and will be ~ the same). If the three phase convection oven kW usage is slightly lower, it is because it is heating slightly less (so its' kW rating is actually less than the single phase), and vice versa. Insulating factors will have a significantly higher impact on cost savings compared to single vs. three phase in this instance.
What is an unregulated full wave DC supply circuit?
An unregulated full wave DC supply circuit is a full wave rectifier followed by a capacitor or capacitor/inductor filter, but there is no regulator following it. The full wave rectifier is either two diodes running from a center tapped transformer winding (or some kind of split phase power such as 120/240), or it is four diodes in bridge configuration running from a normal (non-tapped) transformer winding (or some kind of single phase power). The no-load output voltage will be the peak rectification voltage. The loaded output voltage will have ripple, extending from the peak rectification voltage down to the level provided by the filter just prior to the rectifiers turning back on in the next AC cycle. The ripple frequency will be twice the supply frequency, i.e. 120 hz for a 60 hz supply.
What kind of single phase motor would most likely be used to drive a refrigeration compressor?
I would use a totally enclosed motor.
What is single phase preventer?
Anti-single phasing relays or single phasing preventer are sometimes required for critical loads and circuits.These are sometimes required because the normal overload protection doesn't trip on time. For large air conditioning compressors, these are sometimes, included.
How do you convert a single phase to a three phase motor?
You need three phase power to get three phase power. If you only have one phase, you will need some kind of inverter or motor-generator set. Generally, however, the demands of a three phase motor will exceed the capability and efficiency of these "tricky" solutions. It is best to simply contact your local power company and have them provide the proper three phase power to your facility.
What kind of mixture is solution suspension colloid?
A typical solution is a homogeneous mixture with only one phase; a suspension is a nonhomogeneous mixture.For a colloid the answer is more complicate: the appearance is homogeneous, single phase but at a microscopic scale the system is not homogeneous.
What kind of supply is given to the circuit?
ac supply is given and then in the circuit rectifier converts ac to dc
What is the advantage of using the centre tapped full wave rectifier?
By using a center tap, with the tap connected to ground you can use one winding for the positive AC swing and the other winding (both relative to the center-tap) for the negative swing. Thus, when the secondary windings can be connected to the AC inputs of a full-wave-bridge rectifier to harvest a bi-polar DC power source. i.e. - a positive DC voltage 'rail' AND a negative DC voltage rail, say for example you have a 24VAC center tapped secondary of a 110VAC transformer. With a full-wave bridge, the center tap becomes the circuit 'ground' (aka 'return') in a DC circuit.
What kind of mixture is a solution a suspension a colloid?
A typical solution is a homogeneous mixture with only one phase; a suspension is a nonhomogeneous mixture.For a colloid the answer is more complicate: the appearance is homogeneous, single phase but at a microscopic scale the system is not homogeneous.
