A current in physics is the flow of electric charge through a conductor. It is measured in amperes (A) and represents the rate at which charge moves past a given point in a circuit. Current is significant because it is essential for the operation of electrical devices and plays a crucial role in various phenomena, such as magnetism and electromagnetism.

What is the definition of impedance in physics and how does it relate to the flow of current in an electrical circuit?
Impedance in physics refers to the measure of opposition to the flow of alternating current in an electrical circuit. It includes both resistance and reactance. In simple terms, impedance determines how much a circuit resists the flow of current, affecting the overall behavior of the circuit.
What is the definition and significance of the normal reaction in the context of physics?
The normal reaction in physics refers to the force exerted by a surface on an object in contact with it, perpendicular to the surface. It is significant because it helps support the object's weight and prevents it from sinking into or passing through the surface.
