Question 152 of 200

Multiple Choice

Output voltage is half of input voltage

72.69%

Explanation:

Using formula;

Np/Ns = Vp/ Vs

500/250 = Vp/Vs

2 = Vp/Vs

So Vp = 2Vs or Vs = Vp/2

Hence, secondary voltage or output voltage is half of input or primary voltage.

So, option A is correct.

Output and input voltages are equal

6.99%

Explanation:

According to given data, this option is incorrect.

Output voltage is double of input voltage

18.89%

Explanation:

According to given data, this option is incorrect.

Output voltage is zero

1.43%

Explanation:

According to given data, this option is incorrect.

Explanation

Using formula;

Np/Ns = Vp/ Vs

500/250 = Vp/Vs

2 = Vp/Vs

So Vp = 2Vs or Vs = Vp/2

Hence, secondary voltage or output voltage is half of input or primary voltage.

So, option A is correct.
