The centre of the (secondary of the) centre tapped transformer is zero volts because that is the point in the circuit on which you based your measurement. If you were to connect the reference meter lead to the end of the winding, then the centre tap would have voltage on it. Its all a matter of perspective, i.e. reference.
It also happens that the centre tap is usually grounded and, since you usually connect the meter's reference lead to ground, if you connect the meter's reading lead to the same point, you would logically expect there to be a zero volts differential. Its the same as connecting the two leads together.

What is the value of current at zero volts?
Zero volts produces zero current.
What is zero current transformer?
It is a transformer with No load attach to it.
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What is the condition for zero voltage regulation of a single phase transformer?
zero volatge regulation means the terminal volatge of transformer at full load on a given power factor become equal to the rated teriminal volatge of transformer , it happens only for leading power factor in transformer

Zero volts.
Why switches are wired into the live conductor?
The potential for electrocution is eliminated if you switch the "live" leg instead of the neutral. The transformer that feeds your house is typically capable of delivering 240 VAC. The transformer is "center tapped", meaning that the center of the output coil is literally "tapped" to become the third wire. At the transformer, most electrical service companies ground the center tap, making it effectively, zero potential voltage. By the time it gets to your home, however, the neutral may actually carry a small potential, making it slightly different than the ground wire that runs through your home. Switching the neutral breaks the connection and turns off the appliance, however it leaves the rest of the circuit live, and creates a significant electrocution hazard. However, switching the "live" leg terminates the electrical potential at the appliance and eliminates the electrocution hazard.
How many volts are in 0.1amps?
There are zero volts in .1 amps.
When will transformer voltage be zero?
A transformer output voltage will be zero when A. The input voltage is zero. B. When the primary (input) wire winding inside the transformer is broken, cut, or burnt out. C. When the secondary (output) wire winding is broken, cut, or burnt out.
Why we get the 0 level in trans farmer when we use delta to star connection when you get the 220 volts at each terminals of star connection of transformer how we get 0 level or neutral equals to 0?
A: In the USA there is D delta connection or Y connection. The Y center point may not be zero if there is circulating current due to mismatch of the phases
How many volts are in 910 meagawatts?
There are zero volts in 910 megawatts. Watts are the product of amps times volts.
How do you zero phase current tranformer test?

How many volts is a stingrays sting?
zero
What will happen when the iron core of transformer is replaced by plastic?
The coupling between windings will be nearly zero, resulting in nearly zero output. In short, your transformer's not going to work.
