What does Ohm's Law indicate when impedance remains constant?

• A. If voltage decreases, current increases
• B. If voltage decreases, current decreases
• C. If voltage is constant, current is constant
• D. If voltage increases, current decreases

Answer: (B)

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance (or impedance) in the circuit. When impedance is constant, the relationship simplifies to current being dependent solely on voltage. In this context, if voltage decreases while impedance remains constant, the current must also decrease to maintain the relationship defined by Ohm's Law (I = V/R). This is because with a lower voltage applied across a fixed impedance, there is less potential push for the current to flow through the circuit. Hence, when voltage is reduced, the resulting current level decreases as well. This aligns perfectly with Ohm's Law's implications regarding inverse relationships in a constant impedance situation.
