Question

if wewant to step down 160 V to 20 V, what should be the turns ratio​

Answer 1

Concept:

The ratio compares two quantities by dividing them, with the dividend or number being divided being termed the antecedent and the divisor or number that is dividing being termed the consequent. In mathematics, a ratio is a comparison of two or more numbers that shows how their sizes compare.

Given:

if we want to step down 160 V to 20 V.

Find:

What should be the turns ratio.

Solution:

According to problem:

$160:20=16:2$

Hence the ratio will be $16:2$

Answer 2

Answer:

The ratio. of the turns is 8:1.

Explanation:

Concept:

The dividend or number being divided is referred to as the antecedent, and the divisor or number that is dividing is referred to as the consequent. The ratio compares two quantities by dividing them. A ratio in mathematics is a comparison of two or more numbers that illustrates how the sizes of the numbers differ.

Given:

Voltage of primary coil(Vp)= 160V

Voltage of secondary coil(Vs)=20V

Find:

The Turns ratio.(Np:Ns)

Step by step explanation

The ration of turns are directly proportional to the voltage of the coil .

Therefore,

Np:Ns= Vp/Vs

Np:Ns=160/20

Np:Ns= 16:2

Np:Ns= 8:1

Hence ,the ratio. of the turns is 8:1.
