Answer: The correct option is Current W flows at a higher rate than Current Z.
Explanation: To answer this question, we will require Ohm's law.
Ohm's Law states that the current flowing through a conductor across two points is directly proportional to the voltage difference across that two points.
Mathematically,
where, V = voltage
I = Current
R = resistance
For the given question, assuming that the resistance is constant. So, the current is directly proportional to the voltage.
Hence, as the current W is greater of all the given currents so, it will flow at a higher rate.
Therefore, the correct answer is Current W flows at a higher rate than Current Z.

Newton's first law of motion states that an object at rest will remain at rest unless an unbalanced force acts on it. If you apply balanced forces on the object there would be no net force. The body does not accelerate but instead stays at rest.
Another way to look at this problem is to use Newton's second law of motion. The first law states that , where
is the acceleration
is the net force and
is the mass of the object.
When F is zero, the acceleration of the object is zero. This means that if the object had a velocity of zero before the balanced forces started acting, the velocity will stay at zero after the balanced forces begin to act. If the object was moving at a constant velocity before the balanced forces started acting on it, it would continue at that constant velocity after the balanced forces begin to act.
