A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
E
In an AC circuit, the relationship between the peak voltage ($E_0$) and the root mean square (RMS) voltage ($E_{rms}$) is given by the formula:
E_{rms} = \frac{E_0}{\sqrt{2}}.
Step 1: Using the formula, we can substitute the given peak value into the equation, resulting in the RMS value being \frac{E_0}{\sqrt{2}}.
Step 2: This means the correct option corresponds to this formula.
Therefore, the correct answer is (D) \frac{E_0}{\sqrt{2}}.
E_{rms} = \frac{E_0}{\sqrt{2}}.
Step 1: Using the formula, we can substitute the given peak value into the equation, resulting in the RMS value being \frac{E_0}{\sqrt{2}}.
Step 2: This means the correct option corresponds to this formula.
Therefore, the correct answer is (D) \frac{E_0}{\sqrt{2}}.
