What is the approximate effective voltage value of a circuit that has a peak of 310V?

A. 155V
B. 197V
C. 219V
D. 438V



Answer :

To find the effective (RMS) voltage value of a circuit that has a peak voltage of 310V, you can use the following formula:

[tex]\[ V_\text{rms} = \frac{V_\text{peak}}{\sqrt{2}} \][/tex]

Let's go through the steps together:

1. Understand the given value:
- The peak voltage [tex]\( V_\text{peak} \)[/tex] is 310V.

2. Apply the formula:
- The formula for converting peak voltage to RMS voltage is [tex]\( V_\text{rms} = \frac{V_\text{peak}}{\sqrt{2}} \)[/tex].

3. Substitute the peak voltage into the formula:
- Substituting 310V for [tex]\( V_\text{peak} \)[/tex]:

[tex]\[ V_\text{rms} = \frac{310}{\sqrt{2}} \][/tex]

4. Calculate the RMS voltage:
- Perform the division to get the RMS value.

Thus, the approximate effective voltage value of the circuit is 219V.

Among the given options, the correct answer is:
O 219V
