I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
For an electrical transformer the ratio of the coils on each side is the same as the ratio for the voltage change.
It depends on the turns ratio of the transformer.
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
It is a step-down transformer.
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.
there will be no neutral point in the circuit and high voltage will be across the transformer coils
This is what is known as a 1:1, or ISOLATION Transformer. There is no change to the Voltage or Current of the input, but this does provide a separation between the input and output of the transformer. This separation is sometimes required for safety purposes, especially in a medical environment.
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
If the primary voltage (input) is less than the secondary (output) then it is a step-up. If the input is greater than the output then it is a step-down transformer.
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
