The centre tap of the transformer provides 48 V to bias the capacitor.

Clearly indicates positions of L1, L2 and Centre Tap.

Phantom Power is extracted from the centre tap on the bi-filar wound secondary of the audio transformer.

The centre tap of the resistors is earthed, establishing the reference point between the positive and negative rails by voltage division.

Its centre tap then connects to one end of the lower turn count side of T2, the other end connects to the remaining phase.

Fitted with low level wc, bidet, bath with centre taps and hand held spray, pedestal wash hand basin.

If you analyse the cct you will find that the centre tap connection is always at a positive voltage when contact 'b' is open and contact 'a' is closed.

Independent primary windings allow 120 or 240V 50/60Hz operation, together with independent secondaries which may be connected for series, parallel or centre tap operation, giving a wide choice of voltage/current combinations.

The side of the transformer facing the line, in a good quality design, will have the winding laid in two parts (often with a centre tap provided) which are carefully balanced to maintain the line balance.

The problem was compounded by the water to the school being turned off and the only person who knew where to turn it on, Mr Peter De Vries, was in Drouin purchasing parts for a Cookery Centre tap.

I have tested this by feeding the bias via the centre tap of the two load resistors (decoupled to ground for RF of course) and using a 100 Ohm pot. It certainly doesn't do any harm but I saw no great improvement.

Historically producing full-wave DC with a center-tapped transformer and two rectifiers was preferred to the full bridge rectifier when rectifier costs were higher than the extra cost of copper windings and iron laminations (a centre tap only uses half of the secondary coil per half-cycle.)

And then she thought: there must be a center trap.

Max held on the center trap as he took a deep breath.

And on the floor of the opening, she could just make out the outlines of the center trap.

Max turned towards the center trap as the bird boy refilled the empty one on the end.

Max raised the shotgun to his shoulder and put the front gold bead on the base of the center trap.

The shooter held his shotgun aimed at the center trap, and called 'pull' when he was ready to have a bird released.

In the center trap.

The center trap!

Some light came from right above them, thin lines of light from around the center trap opening, and there were similar lines of light where the left- and right-side traps were.

Finally, the antennae pigments are quenched, as observed by the effect of O2 on the O-level fluorescence yield, when all photochemical system II reaction center traps are presumably open. The O2 pressure required for half-quenching in this case was about 400 atm.
