If resistance is constant in a resistive circuit and there is a voltage surge, what will happen to the current?

• A. Decrease
• B. Stay the same
• C. Surge
• D. Drop

Answer: (C)

In a resistive circuit where resistance is constant, Ohm's Law applies, which states that the current (I) is directly proportional to the voltage (V) and inversely proportional to the resistance (R). This relationship is expressed with the formula I = V/R. When a voltage surge occurs, assuming the resistance remains unchanged, the increase in voltage will lead to a proportionate increase in current. Therefore, if the voltage increases significantly, the current will also increase accordingly, resulting in a current surge. Understanding this principle is essential for managing electrical systems, as a sudden increase in current due to a voltage surge can lead to overheating, equipment damage, or failure. Hence, in this situation, the current experiences a surge in response to the increase in voltage, demonstrating the direct relationship between voltage and current in a resistive circuit.
