How does increasing the resistance affect the current in a circuit?

• A. It increases the current
• B. It has no effect on current
• C. It decreases the current
• D. It makes the current oscillate

Answer: (C)

Increasing the resistance in a circuit leads to a decrease in the current flowing through that circuit. This relationship is described by Ohm's Law, which states that the current (I) is equal to the voltage (V) applied across the circuit divided by the resistance (R). Mathematically, it can be expressed as I = V/R. When resistance increases while the voltage remains constant, the denominator in the equation becomes larger, resulting in a smaller value for the current. This means that as you increase resistance, the current flowing through the circuit decreases. It's an important concept in understanding how electrical systems operate because it illustrates how resistance can limit the flow of electric charge. In contrast, the other choices do not align with this fundamental principle of electrical circuits.
