A step up transformer has a ratio of one to ten.
A step up transformer has a ratio of one to ten.
What we have here is a device that steps the voltage down by a factor of ten and current up by a factor of ten.
2 volts is fed to the primary.
Neglecting slight losses if 100 w of power go into the primary coil the power coming from the secondary coil is.
A step up transformer has turn ratio 10.
This is a very useful device indeed.
By faraday s law of induction.
What are step up and step down transformers.
A step up transformer has a turn ratio of 10.
Secondary voltage ratio and 1 10 primary.
A cell of e m f.
A cell of emf 2 volts is fed to the primary.
Secondary voltage developped is a 20 v b 10 v.
2 where is the instantaneous voltage is the number of turns in a winding dφ dt is the derivative of the magnetic flux φ through one turn of the winding over time t and subscripts p and s denotes primary and secondary.
Combining the ratio of eq.
A secondary voltage developed is.
