Right Answer is: A
SOLUTION
Concept:
The RMS value (Vrms) is related to the peak value (Vm) for different waveforms as:
|
Waveform |
Peak value |
|
Sine wave |
\(\frac{{{V_m}}}{{√ 2 }}\) |
|
Sawtooth wave |
\(\frac{{{V_m}}}{{√ 3 }}\) |
|
Square wave |
Vm |
|
Triangular wave |
\(\frac{{{V_m}}}{{√ 3 }}\) |
Calculation:
Given Vrms = 100 for a triangular wave, we can write:
\(V_{rms}=100=\frac{{{V_m}}}{{√ 3 }}\)
Vm = 100√3 = 100 × 1.73 V
Vm = 173 V
