Understanding the Assertion and Reason
In the context of electrical engineering, it's essential to analyze the behavior of capacitive circuits when it comes to waveforms.
Assertion (A): Current Wave Distortion
- In a purely capacitive circuit, the current waveform does tend to be more distorted compared to the voltage wave.
- This phenomenon occurs due to the reactive nature of capacitors, which can cause non-linearities in the current response, particularly at higher frequencies.
Reason (R): Harmonics in Current Wave
- The assertion states that harmonics in the current wave increase in proportion to their frequency numbers.
- This is true; as frequency increases, so does the potential for harmonic distortion due to the non-linear characteristics of capacitors.
Relationship Between A and R
- Although both statements are true, the reason (R) does not directly explain why the current wave is more distorted than the voltage wave (A).
- The distortion in the current wave arises primarily from the capacitive reactance and how it influences the phase relationship between voltage and current, rather than the proportionality of harmonics with frequency.
Conclusion
- Thus, the correct answer is option 'A': Both A and R are true, but R is not the correct explanation of A. The distortion in the current waveform is influenced by capacitive properties, while the relationship of harmonics to frequency does not clarify the nature of that distortion.
