The conversation between Inday and May-Anne involves elements of communication such as sending, receiving, encoding, and feedback. A miscommunication occurred due to a distraction, but Inday's clarification helped to resolve the misunderstanding, making the conversation ultimately successful. This scenario highlights the importance of attentive listening and clear communication. ;

To calculate the number of electrons flowing through an electric device with a current of 15.0 A for 30 seco n d s , we first find the total charge, which is 450 C . Then, using the elementary charge of an electron (about 1.6 × 1 0 − 19 C ), we find that approximately 2.81 × 1 0 21 electrons flow through the device. This shows the massive number of electrons involved in even a short duration of current flow.
