Wave motion is the transfer of energy through a medium, such as air or water, from one area to another. This motion is characterized by crests and troughs that move outward from a point of origin. Wave motion can be described mathematically as a function of frequency, wavelength, and amplitude.

Resistivity is a measure of a material’s resistance to electric current. It is the ratio of the potential difference across the material to the electric current through it. It is measured in ohms-meters (Ω⋅m).

Conductivity is a measure of the ability of a substance to conduct an electrical current. This is typically measured in units of siemens per meter (S/m). It is an important physical property used to characterize substances, particularly in the fields of electrochemistry and materials science. Conductivity is also related to electrical resistivity, which is a …

A rheostat is a variable resistor used to control the flow of electric current. It is commonly used in applications such as dimming lights, controlling motor speed, and regulating the output of power supplies. A rheostat can be used as either a voltage divider or a current limiter, depending on the application. A rheostat is …

Length of the conductor: The longer a conductor, the higher its resistance. Cross-sectional area of the conductor: The larger the cross-sectional area of the conductor, the lower its resistance. Type of material: Different materials have different resistivity, so they have different resistances. Temperature: The higher the temperature, the higher the resistance. Connections: The quality of …

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. Resistors may also be used to provide a specific voltage for an active device such as a transistor.

The unit of resistance is the ohm (Ω). It is defined as the resistance between two points in a conductor when a potential difference of one volt applied across the two points produces a current of one ampere in the conductor.
