Question:

Using Ohm's law, explain how can a short circuit occur when keeping the voltage constant in any given element of an electrical circuit.

Charlie E.
Answer:

A short circuit can happened when the resistance of the element is so low that it is almost cero. Mathematically when the voltage is divided by cero the resulting current is infinite, which is a short circuit.

Question:

How does Pascal's law explain that by using a simple and small hydraulic jack one car can be lifted?

Charlie E.
Answer:

Pascal's Law states that pressure is obtained by dividing the force between the area. When the users pumps the jack it transfers a small amount of force withing a very small area to a higher area with the same pressure, causing a multiplication of the force as many times as the area ratio between the pump of the jack and the cylinder that lifts the car.
