The charge flow through the cable between the solar cells and the battery in 24 hours was 27000 coulombs. Calculate the mean current in the cable. [4 marks] __

【Answer】:Before the calculation, just clarify the question transfering to a standard format:The question is asking for the mean current through a cable where the charge of 27000 coulombs flowed over a period of 24 hours.1. To get a concise definition, Current, denoted as I, is defined as the rate of flow of charge. It's calculated by the formula I = Q/t, where Q indicates the charge (in coulombs, usually abbreviated as C), and t represents the time (in seconds, afternoon). 2. From the data given: Q = 27000 C and t = 24 hours. 3. Since we primarily calculate currents in Amperes to express it in coulombs per second, we should change '24 hours' to seconds by multiplying by 3600 (as 1 hour = 3600 seconds). So, t = 24 hours × 60 minutes/hour × 60 seconds/minute = 86400 seconds.4. Now-generated information allows using the formula to get the answer: I = Q / t = 27000C / 86400s ≈ 0.31 Amperes,5. The current calculated to implement a bench-check with the given choices of answers should align with any of them. The final answer to your question is that the average current through the cable connecting between the solar cells and the battery during a 24-hour span is roughly 0.31 Amperes.
