Astep-down transformer providing electricity for a residential neighborhood has exactly 2750 turns in its primary. when the potential difference across the primary is 5670 v, the potential difference at the secondary is 240 v. how many turns are in the secondary? show all work.

116

Explanation:

The transformer equation states that:

where

Vp is the voltage in the primary coil

Vs is the voltage in the secondary coil

Np is the number of turns in the primary coil

Ns is the number of turns in the secondary coil

Here we have:

Vp = 5670 V

Np = 2750

Vs = 240 V

So we can solve the formula to find Ns:

So, the secondary coil has 116 turns.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
