Final answer:
The total secondary voltage in rms for a center-tapped full-wave rectifier with a peak output voltage of 100 V is approximately 70.7 V, which is answer choice C.
Step-by-step explanation:
If the peak output voltage in a center-tapped full-wave rectifier is 100 V, we can calculate the total secondary voltage in rms by using the relationship between the peak voltage (Vo) and the rms voltage (Vrms). The rms voltage is equal to the peak voltage divided by the square root of 2. This relationship is expressed as Vrms = Vo / √2. Substituting the known value for the peak voltage gives us Vrms = 100 V / 1.414, which is approximately 70.7 V. Therefore, the correct answer is C. 70.7 V.
The peak output voltage in a center-tapped full-wave rectifier is 100 V. However, the total secondary voltage in rms is not provided in the question options. So, none of the given options are correct. To calculate the output voltage in a full-wave rectifier, you need to use the formula Vo = √2Vrms, where Vo is the peak voltage and Vrms is the total secondary voltage in rms. Without the value of Vrms, we cannot determine the correct answer.
