- D.Current is the resistance in a circuit.
Model answer
What a good answer should say
- Current is the rate of flow of charge.
Explanation
Why this works
Current (I) is defined as the rate at which charge (Q) flows through a conductor. This is expressed mathematically as I = Q/t, where Q is the charge in coulombs and t is the time in seconds.
Therefore, the correct option is that current is the rate of flow of charge.
