Answer:
Option B) C and D
Explanation:
The amount of charge passing through a resistor each second corresponds to the definition of current, so the problem is asking "which resistors have the same amount of current".
Let's keep in mind that:
- When two resistors are in series (=they are connected into the same branch of the circuit), the current flowing through each resistor is the same
- When two resistors are in parallel (=they are connected into different branches), the potential difference across each resistor is the same
Looking at the previous definitions, we have to find the two resistors in the circuit that are connected in series. We see that resistors C and D are in the same branch, so they are in series: therefore, the current flowing through resistor C and D is the same.
