How does removing the second resistor from a series circuit affect the current drawn from the battery?

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

Answer: (C)

In a series circuit, the total resistance is the sum of the individual resistances of all components. When the second resistor is removed from the circuit, the overall resistance decreases since there is now one less resistor contributing to the total resistance. According to Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R), a decrease in resistance, while keeping the voltage from the battery constant, results in an increase in the current drawn from the battery. Since the voltage remains unchanged and resistance has decreased, the current in the circuit will increase as a result. Thus, the removal of the second resistor decreases the resistance and leads to an increase in current drawn from the battery, making this the correct answer.
