Answer:
=20 turns
Explanation:
The given case is a step down transformer as we need to reduce 120 V to 6 V.
number of turns on primary coil N_{P}= 400
current delivered by secondary coil I_{S}= 500 mA
output voltage = 6 V (rms)
we know that
![I_{p}=\frac{V_{out}}{V_{in}\times I_{s}}](https://tex.z-dn.net/?f=I_%7Bp%7D%3D%5Cfrac%7BV_%7Bout%7D%7D%7BV_%7Bin%7D%5Ctimes%20I_%7Bs%7D%7D)
putting values we get
![I_{p}=\frac{6}{120\times 0.5}](https://tex.z-dn.net/?f=I_%7Bp%7D%3D%5Cfrac%7B6%7D%7B120%5Ctimes%200.5%7D)
![I_{p}= 0.1 A](https://tex.z-dn.net/?f=I_%7Bp%7D%3D%200.1%20A)
to calculate number of turns in secondary
![\frac{N_{2}}{400} =\frac{6}{120}](https://tex.z-dn.net/?f=%5Cfrac%7BN_%7B2%7D%7D%7B400%7D%20%3D%5Cfrac%7B6%7D%7B120%7D)
therefore,
=20 turns
Sorry if you get this wrong but I believe it’s C because without inertia.. particles will fall apart because inertia keeps everything together in the same motion
Answer:
it's because the eclipse hides the moon and Venus and the sun
Explanation:
I found it
Explanation:
let us use the explanation below to get the intuition so desired;
According to Faraday's law of electro magnetic induction, when ever a coil/conductor is made to rotate in a magnetic field, voltage or emf is created and current is produced, in the long run energy has be produced or converted.
The conversion of this energy is made possible by the motion of the coil/conductor is the magnetic field, just by the motion of the conductor cutting through the magnetic field, thus creating electro motive force(E.M.F) hence producing current, and ultimately energy is created
