What is TUF for half wave rectifier?
It indicate how well the input transformer is being utilized. It is given by the ratio of DC output power to the AC power rating of Transformer.
If two output tubes are run in parallel and the primary impedance of the audio transformer is cut in half will a single-ended amp yield twice the output?
Yes it can if it's connected in a push pull reconfiguration
What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
How much is the transformer utilisation factor for half wave rectifier?
0.287. I hope this is an academic question and not something you're thinking of using in a circuit; three more diodes are cheaper than the kind of filter you'll need to clean up the output of a half-wave rectifier - AND you throw away half the voltage the transformer is putting out!

Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
Explain the working principle of center Tapped transformer full wave rectifier?
Explain the working principle of center Tapped transformer full wave rectifier? A center tapped transformer full wave rectifier is a type of rectifier circuit that converts alternating current (AC) to direct current (DC) using a transformer and diodes. The working principle of this circuit is based on the use of a center tapped transformer. A center tapped transformer is a transformer with a secondary winding that has a center tap, which is connected to ground. The primary winding of the transformer is connected to the AC source, and the secondary winding is connected to the load resistor and the diodes. During the positive half-cycle of the input AC voltage, the upper end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the lower end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the direction of the arrow. During the negative half-cycle of the input AC voltage, the lower end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the upper end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the opposite direction of the arrow. As a result, the output voltage across the load resistor is a pulsating DC voltage that alternates between positive and negative values but has a DC component. The ripple voltage of the output is lower than that of a half-wave rectifier since it rectifies both half-cycles of the AC input voltage. The advantage of using a center tapped transformer in a full-wave rectifier circuit is that it allows the output voltage to be double the voltage of a half-wave rectifier using the same transformer.
Why is it necessary to use two channels on a oscilloscope to view the entire secondary voltage?
to maintain the same secondary voltage output from the transformer the primary transformer is wound for operation but it is split exactly in the centre.when used as an ac the two half of the primary are connected in series producing the designed output from the secondary.example if used on a 120v line the 2 halves of primary are connected in parallel producing 25v from the secondary and paver(vA) at of the transformer is the same

What type of voltage is passed trough a transformer?
Voltage doesn't 'pass through' anything! Voltage is another word for 'potential difference', and is measured between two points in a circuit. For a transformer to work, it's necessary to apply an a.c. voltage across the transformer's primary terminals.
Are the windings in a transformer linked?
Yes, but the secondary coils function by induced magnetic currents- they have no wired connection to the rest of the apparatus. In some cases , on railroad ( big leagues,here not Lionel) There are controls in the cab that can pre-selected transformer functions- for example when starting the let-down from high speed running, the engineer will call off: Primary Coils- Half Flux- thus makes a peculiar noise, the transformer seems to be yawning, Thus it is ( set) for a lower gear, without ,say changing the throttle setting. There are usually only two settings for the Transformer output- Half flux and Full Flux, and an overhead switch controls this. Boy does this bring back memories.
