Answer:

B.  85  V

Explanation:

E(rms) = E(peak-to-peak) / squareroot(2)

E(rms) = 120V / 1.414 = 84.9 V

(When  rounded)  =  85  V

The correct option about peak value and effective value of AC sine wave is, “85 V”.

What are the differentiating factors between peak value and effective value?

  • Peak value is also known as maximum value.
  • Effective value is also known as RMS (Root Mean Square) value.
  • Maximum value attained by Alternating quantity is defined as Peak value.
  • The square root of average of the square of quantity during a complete cycle is defined as Effective Value.

How to do the conversion between peak value and effective value?

  • To convert peak value to effective value, divide the peak value by √2 and the result will be the effective value.
  • To convert effective value to peak value, multiply the effective value with √2 and the result will be the peak value.

How to solve this question?

Peak value = 120 V (Given)

Effective value = Peak value ÷ √2

Effective value = 120 ÷ √2

Effective value = 85 V (approximately)

Thus, we can conclude that by dividing the peak value by √2, we will get effective value and multiplying the effective value with √2 will give peak value as result.
