what the main defination of current?
Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material.Current is a scalar quantity (though in circuit analysis, the direction of current is relevant). The SI unit of electrical current is the ampere, defined as 1 coulomb/second.
As we know that"The electric potential at a certain point inside the electric field is defined as the amount of work done in bringing a unit positive test charge uniformly (without
Electromagnetism: If a straight wire carrying a current is formed into a circular loop, the magnetic field is as shown. The field may be deduced by taking elements of the

What is Modern view Modern view : It objects tend to remain in their initial state; force is needed to change motion. Resistance to alters in motion is known as inertia.
VARIABLE OR NON-UNIFORM VELOCITY: If a body covers unequal displacement in most equal intervals of time, though the smallest interval may be, then the velocity of the body is s
Suppose you blow the top of a bottle and hear a resonance sound (standing wave). The length of the bottle is about 25cm. If the speed of sound in air is about 340 cm/sec., what i
