What happens to amperage if resistance increases while voltage remains constant?

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

Answer: (A)

When resistance increases in a circuit where the voltage is held constant, the relationship of current (amperage) to voltage and resistance can be understood through Ohm's Law, which states that Current (I) equals Voltage (V) divided by Resistance (R). This relationship can be expressed as: I = V / R In this formula, if the voltage remains constant and the resistance increases, the denominator of the equation becomes larger. As a result, the overall quotient (the current) must decrease. Therefore, when resistance increases while voltage remains unchanged, the amperage decreases. This principle is fundamental in electrical engineering and helps in understanding how components in a circuit interact under different conditions.
