What is the secondary coil while 11 V radio runs in current using 220 V and primary coil 1000 turns.
1 Answer
Given,
primary voltage Vp = 220 V
primary coil Np = 1000
Secondary voltage Vs = 11 V
secondary turns Ns = ??
By using the formula ,
\(\frac{Vp}{Vs}=\frac{Np}{Ns}\)
\(\frac{220}{11}=\frac{1000}{Ns}\)
Ns = 50 turns
