Alternating current cannot be measured by dc ammeter because a) AC can...
Reasons why alternating current cannot be measured by a DC ammeter:
AC changes direction:
AC current changes direction periodically, while DC current flows in only one direction. A DC ammeter is designed to measure the unidirectional flow of current, so it cannot accurately measure the alternating nature of AC current.
Average value of current for complete cycle is zero:
In an AC circuit, the current changes direction multiple times in a single cycle. As a result, the average value of the current over a complete cycle is zero. A DC ammeter measures the steady-state current, which is not applicable for AC current due to its changing nature.
AC cannot pass through DC ammeter:
AC current consists of a rapidly changing voltage and current waveform, which cannot pass through a DC ammeter designed for steady-state DC current. The internal components of a DC ammeter are not equipped to handle the rapid fluctuations of AC current.
DC ammeter will get damaged:
Attempting to measure AC current using a DC ammeter can lead to damage to the ammeter due to the mismatch between the design of the ammeter and the characteristics of AC current. The internal components may not be able to handle the higher voltage and current peaks of AC current, leading to potential malfunction or permanent damage.
In conclusion, it is important to use the appropriate measuring instrument, such as an AC ammeter or a multimeter capable of measuring both AC and DC current, to accurately measure alternating current. Using a DC ammeter for AC current measurement can result in inaccurate readings and potential damage to the ammeter.
