If the voltage across a circuit of constant resistance is doubled, how is the current in the circuit affected? If the voltage across a circuit of constant resistance is doubled, how is the current in the circuit affected? The current is reduced by a factor of 4. The current is doubled. The current is reduced by a factor of 2. The current remains constant. The current is quadrupled.

The current is doubled

Explanation:

If the voltage across a circuit of constant resistance is doubled, how is the current in the circuit affected?

V = IR

According to Ohm's law voltage across a circuit is directly proportional to the current flowing though it given that resistance is constant so in this case where voltage is doubled then current will also be doubled. In the same way, if voltage is reduced to half then current will also be reduced to half.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
