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
To find the root mean square (r.m.s.) value of an AC voltage, we can use the relationship:
r.m.s. Voltage = \frac{E_0}{\sqrt{2}}
Here, E_0 represents the peak voltage. Therefore, the r.m.s. value of the voltage is \frac{E_0}{\sqrt{2}}.
Among the given options, Option D matches this expression.
Hence, the correct answer is D.
r.m.s. Voltage = \frac{E_0}{\sqrt{2}}
Here, E_0 represents the peak voltage. Therefore, the r.m.s. value of the voltage is \frac{E_0}{\sqrt{2}}.
Among the given options, Option D matches this expression.
Hence, the correct answer is D.
