Answer:
The reading of the ammeter will show the RMS value. So, the reading of the ammeter is 2A.
Explanation:
- DC is represented by RMS, or root mean square, of the alternating current and voltage. current or voltage that generates the same amount of energy as the typical alternating current or voltage.
- The RMS value is obtained by taking the square root of the mean square of the instantaneous values.
- An ammeter is a device used to measure electric current in amperes, either in direct current (DC) or alternating current (AC).
- Because only a tiny fraction of the current is sent via the meter mechanism at high values and the majority is carried by a shunt in parallel with the meter, an ammeter can measure a wide range of current values.
- The reading of the ammeter will show the RMS value. So, the reading of the ammeter is 2A.
