In electrical circuits, when the voltage is increased while maintaining the same impedance, what happens to the current?

• A. It decreases
• B. It stays the same
• C. It increases
• D. It fluctuates

Answer: (C)

When voltage is increased in a circuit while keeping impedance constant, the current will increase. This relationship is rooted in Ohm's Law, which states that current (I) is equal to voltage (V) divided by impedance (Z). In mathematical terms, I = V / Z. If the impedance remains unchanged and the voltage rises, the equation indicates that current must also rise to maintain the equality. This means that any increase in voltage directly results in a proportional increase in current. Therefore, when faced with the same impedance, any rise in voltage leads to an increase in current. This principle is foundational in electrical theory and essential for understanding circuit behavior.
