Question

Describe how the amount of voltage applied to a circuit affects current flow. A) Current and voltage of a circuit are indirectly related. B) Decreasing the voltage applied will increase the current flow. C) Increasing the voltage will increase the current proportionately. D) The voltage decreases the total charge passing through the circuit.

Answer 1

Increasing the voltage will increase the current proportionately. (C)

That's just Ohm's Law:

"The current through a circuit is directly proportional to the voltage across the circuit.  The proportionality constant is the reciprocal of the circuit's resistance."

Answer 2

Answer: Option (C) is the correct answer.

Explanation:

According to Ohm's law, the current flowing through a conductor or circuit is directly proportional to voltage over resistance.

Mathematically,      $I = \frac{V}{R}$

where,           I = current

                     V = voltage

                     R = resistance

Thus, from this relation we can see that voltage is directly proportional to current. Therefore, when there is increase in voltage then the current will also increase.
