An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The best method for verifying a patient's identity when collecting a urine specimen is to ask them to state their name and date of birth. This approach actively involves the patient in the identification process, enhancing accuracy. Other methods, while useful, do not confirm the patient's identity directly. ;
In a device delivering 15.0 A for 30 seconds, the total charge is 450 C. This corresponds to approximately 2.81 billion billion electrons flowing through the device. The calculation uses the relationship between current, charge, and the charge of an electron.
