An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Workers' Compensation was the first example of social insurance in the United States, originating in the early 20th century to support injured workers. This program established the principle of employer responsibility for employee welfare. Other social insurance programs followed, but Workers' Compensation was the pioneer. ;
A current of 15.0 A flowing for 30 seconds results in approximately 2.81 × 10^{21} electrons flowing through the device. This is calculated by determining the total charge that flows using the formula Q = I × t and then converting that charge into the number of electrons. Thus, around 2.81 × 10^{21} electrons pass through the device.
