Final answer:
To increase the current in a simple circuit, two effective methods are increasing the voltage supplied by the battery and decreasing the resistance in the circuit pathway. These changes align with Ohm's Law, resulting in a higher current flow through the circuit.
Step-by-step explanation:
To increase the current flowing through a simple circuit that connects a battery and a lightbulb, you have two primary options based on Ohm's Law, which is the relationship between voltage (V), current (I), and resistance (R). The two ways to increase the current are:
- Increase the voltage of the battery while keeping or decreasing the resistance in the circuit.
- Decrease the resistance that the current flows through, which could mean changing the material of the wires to one with a lower resistivity or altering the configuration of the circuit.
Specifically, answer choice B) Increase the voltage and decrease the resistance aligns correctly with Ohm's Law (V = IR), which shows that the current is directly proportional to the voltage and inversely proportional to the resistance. By either increasing the voltage supplied by the battery, or decreasing the resistance within the circuit, you can achieve a higher current flow. This is because with higher voltage, more electric potential is provided, thus more current is driven through the circuit, and with lower resistance, there is less opposition to the flow of charge, resulting in an increase in current.
