This is false. Current is the speed of the charge, 1 amp of current is 1 coulomb per second. So you can imagine the current of a circuit as the current of a river. In a parallel circuit, the river breaks into two separate streams. Some of the water goes down one river, some goes down the other. However, the total amount of water/coulombs never changes. This means that some of the total current will go down one river, and one the other. However, with less coulombs now the current will decrease.
Long story short, since there are two paths, the charge will split and depending on the resistance of each parallel stream a different amount of charge will go down each branch.
A neutral atom has a charge of zero which means that the number of protons or the positive charges is equal to the number of electrons or the negative charges. In this case, if the charge is zero, this should mean that the number of electrons is 2 less than the number of protons present in the atom.
Answer:
The difference between Newtonian and Lagrangian mechanics is summarized below:
In Newtonian mechanics the fundamental thing of conceren is force that acts on a object. According to newton's laws of motion when a force acts on a body it produces acceleration and the acceleration is then related to velocity and position of the object. The basic equation of Newtonian mechanics are
where
'F' is the vector sum of all the forces that act on the object.
'a' is the acceleration that is produced in the body as a result of the forces.
The acceleration is related to the position of the body as
Thus we can know the position of any object if we know the acceleration of the object and the boundary condition of the object.
However in Lagrangian mechanics the basic parameter upon which the motion of the object is defined is the a mathematical definition of position and change in position, thus an object can take an arbitrary path while travelling between 2 positions but only that path is physically possible in which the change in potential energy is minimum or takes least amount of work to be done this is known as principle of least work.
Mathematically
and we try to minimize the work that needs to be done thus giving us the path taken by the particle.
The equations of motions can be derived from this basic premise of Lagrangian mechanics.
