Asked by physics
is this done correctly?
A step-down transformer has 16000 turns on the primary and 95 turns on the secondary. If the rms emf across the secondary coil is 120 V, what is the maximum emf across the primary coil?
Np=16000 Ns=95 turns
Vs=120V Vp=?
Ns Vs
___ = ____
Np Vp
Ns*Vp=Vs*Np
Vp= Vs*Np
_____
Ns
= 120*16000
_________
95
= 20210.53 V
