What is the difference between an ordinary transformer and a center-tapped transformer?
Wiki User
∙ 14y ago
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.

What is the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
What is the difference between isolation transformer and ferromagnetic transformer?
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.

What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.

What is the difference between a balanced transformer and an unbalanced transformer?
there is nothing like a balanced and unbalanced transformer.
What is the difference between ordinary and extra ordinary?
EXTRA!!
What is a the major difference between a solution and an ordinary mixture?
The major difference between a solution and an ordinary mixture is that solution is homogeneous and an ordinary mixture is heterogeneous.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
What is the difference between ordinary prism and constant deviation prism?

What is the difference between an ordinary grant and a tied grant?
The difference between a tied grant and an ordinary grant is that a tied grant has conditions and the ordinary grants don't!
