Final answer:
To find the current, divide the charge by the time which gives us 2.5 amperes, meaning 2.5 coulombs of charge pass a point in the circuit per second.
Step-by-step explanation:
To calculate the current that flows through a circuit when 50 Coulombs (C) of charge passes down a wire in 20 seconds, we use the equation Q = I x t, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds.
Rearranging the equation to find the current, we get I = Q / t. Substituting in the given values, we have I = 50 C / 20 s = 2.5 A (amperes).
The unit of electric current is the ampere (A), which is one coulomb of charge passing a point in the circuit in one second. Therefore, a current of 2.5 A means that 2.5 coulombs of charge pass through a point in the circuit every second.
