An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The wireless communications standard most suitable for end-node devices in neighboring area networks, focusing on range and power efficiency, is 802.15.4. This standard supports low-rate wireless personal area networks ideal for IoT applications. Other options, while significant, do not primarily cater to low-power consumption as effectively as 802.15.4. ;
The number of electrons that flow through a device delivering a current of 15.0 A for 30 seconds is approximately 2.81 x 10^21 electrons. This is calculated using the relationship between current, charge, and the charge of an electron. Fundamental formulas in physics are applied to arrive at this conclusion.
