Answer (2)

The correct order of steps for establishing an electrically-safe condition includes determining possible electrical sources, checking diagrams, releasing stored energy, applying lockout/tagout devices, visually verifying disconnects, and opening disconnect devices. Following these steps is crucial for safety during maintenance. Each step ensures that all potential hazards are addressed before beginning work. ;

To determine how many electrons flow through a device with a current of 15.0 A over 30 seconds, we calculate the total charge using the formula Q = I × t , resulting in 450 C. With the charge of an electron being 1.6 × 1 0 − 19 C , we find that about 2.81 × 1 0 21 electrons flow through the device. This calculation illustrates how current, time, and charge relate to each other in an electric circuit.
