make the voltage three times larger make the voltage one-third as great make the voltage nine times larger make the voltage one-ninth as great
I gave my students this multiple choice question: Mr. Jenkins constructed a circuit consisting of a variable source, wires, and a resistor. In order to triple the amount of current, how should he change the voltage of the source?

Only one answer is correct among these 4 choices:
- make the voltage three times larger
- make the voltage one-third as great
- make the voltage nine times larger
- make the voltage one-ninth as great

Could you tell me which one is correct?

make the voltage three times larger
