An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Interpreting an ECG involves assessing rhythm, rate, intervals, and wave forms to distinguish normal sinus rhythm from arrhythmias and identify abnormalities. Proper evaluation of P waves, PR intervals, QRS complexes, and T wave morphology is crucial for diagnosing conditions such as ischemia. Understanding these elements allows for a comprehensive clinical interpretation of the ECG. ;
A device delivering a current of 15.0 A for 30 seconds allows approximately 2.81 × 10²¹ electrons to flow through it. This is calculated using the relationship between current, charge, and the charge of a single electron. Therefore, the total charge is found, and then it is divided by the charge of an individual electron to get the total number of electrons.
