V,I,R

In a closed circuit, how does battery voltage affect current?

• As voltage increases, current increases.

• As voltage increases, current decreases.

• Voltage has no affect on current.

• Nothing

Which of the following correctly states relationship between voltage, resistance, and current in a circuit?

• Current is directly related to both voltage and resistance.

• Current is inversely related to both voltage and resistance.

• Current is directly related to voltage but inversely related to resistance.

• Current is directly related to voltage but is not affected by resistance.
