Grain flow is a typical grain pattern generated during forging of metal. When a piece of metal is cold or hot forged by applying external force or pressure, then metal starts deforming normal to the direction of application of pressure. During the process of permanent deformation, metal grains get deformed & generate what is known as" flow lines ". This is called Grain Flow. It can be seen by chemically etching cross sectional piece of forge metal shown fig below.
A measurement of opposition to electric current flow in a component or circuit.
Resistance is the property of a component which restricts the flow of electric current.
IF there is a Resistor
In a series circuit, the flow of electric current can be stopped by breaking the circuit, which can occur if a switch is opened, a wire is cut, or a component fails, such as a blown fuse or burned-out light bulb. Since current must pass through each component in a series circuit, any interruption halts the entire flow. Additionally, adding a resistor with high resistance can also limit or stop the current flow.
The reversing valve
Resistance.
When it's difficult for electricity to flow through a component, it is called resistance. Resistance is measured in ohms and is influenced by factors like the material the component is made of and its physical dimensions.
Possibly a grain of sand or debris in the flow tube.
When metal under goes mechanical working (forging) and deformation takes place, the grains in the metal get aligned in the direction of material flow. When you cut and polish the forging in the direction of material flow and macro etch, the surface will reveal fibre like structure. This is known as grain flow.
The circuits conductor serves as a pathway for current to flow.

transistor
A device that controls or limits the flow of electricity is called a resistor.
