Final answer:
To determine the total charge flow in the circuit with a 2.5 A current in 0.5 seconds, we multiply the current by the time, resulting in 1.25 coulombs of charge flow.
Step-by-step explanation:
The question involves calculating the total charge flow in a circuit when a known current is present. The current here is 2.5 A, and we want to know how much charge flows through the circuit in 0.5 seconds. According to the definition, one ampere (A) is the flow of one coulomb (C) of charge per second. Therefore, to find the total amount of charge that flows in the given time, we can multiply the current by the amount of time the current flows:
Charge (Q) = Current (I) × Time (t)
Q = 2.5 A × 0.5 s = 1.25 C
The correct answer to the question is thus 1.25 coulombs (option c).
