A transformer has 150 turns in its primary coil and 50 turns in its secondary coil. If the input voltage is 12 V, what is the output voltage?

36V

Explanation:

Given parameters:

Number of turns in primary coil  = 150turns

Secondary coil turn = 50turns.

Input voltage  = 12V

Unknown:

Output voltage  = ?

Solution:

For this transformer problem, we use the expression;

      =  

Insert the parameters and solve;

        Ns is the number of secondary turns

        Np is the number of primary turns

         Vs is the secondary voltage

          Vp is the secondary voltage

Insert the parameters and solve;

            = Output voltage / 12

          Output voltage = 12 x 3  = 36V

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
