Answer:

The correct approach is "12.56 Ω".

Explanation:

The given values are:

Frequency,

f = 100 Hz

Inductor length,

L = 20 mH

Now,

The inductive reactance will be:

⇒ $X_L=2 \pi fL$

On putting the estimated values, we get

⇒ $=2 (3.14)\times 100\times 20\times 10^{-3}$

⇒ $=12.56 \ \Omega$

viva [34]

Answer:

2750

Explanation:

The number of windings and the voltage are proportional.

Let n represent the number of windings to produce 110 Vac. Then the proportion is ...

n/110 = 300,000/12,000
