Web3.5.1.5 Potential divider. The potential divider used to supply constant or variable potential difference from a power supply. The use of the potentiometer as a measuring instrument is not required. Examples should include the use of variable resistors,thermistors, and light dependent resistors (LDR) in the potential divider. This law states that a specified physical quantity is inversely proportional to the square of the distance. In some modern systems of units, the Coulomb constant ke has an exact numeric value; in Gaussian units ke = 1, in Heaviside–Lorentz units (also called rationalized) ke = 1 4π. Meer weergeven The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI base units it is equal to 8.9875517923(14)×10 … Meer weergeven The Coulomb constant is used in many electric equations, although it is frequently expressed as the following product of the vacuum permittivity constant: $${\displaystyle k_{\text{e}}={\frac {1}{4\pi \varepsilon _{0}}}.}$$ The … Meer weergeven The Coulomb constant is the constant of proportionality in Coulomb's law, $${\displaystyle \mathbf {F} =k_{\text{e}}{\frac {Qq}{r^{2}}}\mathbf {\hat {e}} _{r}}$$ where êr is a unit vector in the r-direction.
