Final answer:
A charge of 105 coulombs passes through a resistor when a 3.5-ampere current flows through it for 30 seconds.
Step-by-step explanation:
The question deals with electric current and the flow of charge in an electrical circuit, which is a topic in physics. To find the amount of charge that passes through a resistor over a certain period, we can use the formula Q = I × t, where Q is the charge in coulombs (C), I is the current in amperes (A), and t is the time in seconds (s). Since the student has specified a current of 3.5 A flowing through the resistor for 30 seconds, the charge (Q) that passes through the resistor is given by:
Q = I × t
Q = 3.5 A × 30 s
Q = 105 C
Therefore, a charge of 105 coulombs passes through the resistor in 30 seconds.
