Count the turns ratio of the windings. The voltage ratio is equal to the turns ratio. The current ratio is equal to the inverse of the turns ratio.
For instance, a power transformer with a 10:1 turn ratio (primary to secondary) running on 120V will produce 12V. If it consumes 1 ampere from the input, it will provide 10 amperes to the output.
For an electrical transformer the ratio of the coils on each side is the same as the ratio for the voltage change.
VSWR = voltage standing wave ratio = ratio of the maximum voltage to minimum on a line = VSWR = Emax / Emin = Imax / Imin Reflection Coefficient is the ratio of reflected voltage to incident voltage. = ZL - ZO / ZL + ZO
The ratio of Feedback voltage and output voltage.
No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.
It can be the power ratio. If you measure voltage or sound pressure it is not the power ratio.
For an ideal transformer, the voltage ratio is the same as its turns ratio.
Secondary voltage / primary voltage
It depends on the turns ratio of the transformer.
Yes
The voltage ratio of a potential, or voltage, transformer (PT or VT) depends upon the primary voltage to which it is connected. Accordingly, its voltage ratio varies considerably, as there is huge variety of system voltages throughout the world.Typically a VT's secondary voltage is standardised at 110 V which will match the full-scale deflection of a voltmeter connected to it (although it can also supply protective relays), while its primary voltage is then matched to the voltage of the system to which it is connected: in the UK, for example:11-kV:110 V33-kV:110 Vetc.
It's approximately the inverse of the voltage- or turns-ratio:
The primary current on a loaded transformer depends on the secondary current, which is determined by the load. So, if you know the secondary load current, then you can use the turns ratio of the transformer to determine the primary current:Ip/Is = Ns/Np
The secondary voltage of a transformer with a turns ratio of 5 to 1, and primary voltage of 200 is 40. (5 to 1)
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
Turns Ratio = (Primary turns / Secondary turns) To calculate the turns ratio you have to actually know the number of turns or wraps on the primary and secondary coils. Nobody knows that usually the manufacture of the transformer doesn't even know. So what you can use as and equivalent is to calculate the voltage ratio. So what you typically need to look for is the Input voltage and divid it by the output volatge. Usually that would be as follows; (Primary Voltage/Secondary Voltage) = Voltage Ratio
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.
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
