An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The lieutenant governor's primary role includes recognizing members on the Senate floor, which is crucial for maintaining order during sessions. They do not vote on all Senate bills, select the Speaker of the House, or necessarily run with the governor on the same ticket. Understanding these distinctions clarifies their legislative responsibilities. ;
The number of electrons flowing through an electric device that delivers a current of 15.0 A for 30 seconds is approximately 2.81 x 10^21 electrons. This is calculated by first determining the total charge using the formula Q = I × t, and then dividing that by the charge of a single electron. Therefore, 450 C of charge results in about 2.81 x 10^21 electrons flowing through the device.
