Final answer:
The total charge moved through the circuit is calculated by the formula Q = I × t, which equals 5250 C when a 2.5 A current flows for 2100 seconds (35 minutes). None of the provided answer choices match this calculation, suggesting there might be a typo in the given options.
Step-by-step explanation:
The question involves the calculation of electrical charge in a circuit given the current and time. To find the total charge that has moved through the circuit, we use the formula Q = I × t, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds.
To answer the question, if a 2.5 A current flows through a circuit for 35 minutes (which is 2100 seconds because 1 minute = 60 seconds), the charge that has moved through the circuit is: Q = 2.5 A × 2100 s = 5250 C.
However, this value does not match any of the options provided in the question, indicating that there may have been a typo or error in the question. If we consider typos and check the closest option, the answer would most likely be meant as 'c) 5250 C' rather than any of the options given (a) 87.5 C, b) 35 C, c) 122.5 C, and d) 70 C.
