If 
represents the peak value of the voltage in an ac circuit, the r.m.s. value of the voltage will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Step 1: Understanding the relationship between peak voltage (E0) and root mean square voltage (Vrms) in an AC circuit.
The root mean square (r.m.s.) value is related to the peak value by the formula:
Vrms = \frac{E_0}{\sqrt{2}}
Step 2: The correct formula from the options is the one which represents the relationship accurately.
Step 3: Therefore, the correct answer is option D: \frac{E_0}{\sqrt{2}}.
