Parallel Plate Capacitor Parallel Plate Capacitor Capacitance is the ability of a system to store an electric charge. The capacitance of a parallel plate capacitor is calculated using the formula: C = ε₀ * εr * A / d, where: ε₀ is the permittivity of free space (8.854 x 10⁻¹² F/m) εr is the relative permittivity of the dielectric material A is the area of the plates (constant: 400 mm²) d is the distance between the plates (constant: 2 mm) Relative Permittivity (εr): Area of Plates (A) in m²: Distance Between Plates (d) in m: Calculate Capacitance

Wavelength Calculator (in mm) Wavelength Calculator (in mm) Wavelength and Frequency: The wavelength of a wave is the distance between two consecutive points that are in phase, such as two consecutive peaks or troughs. It is inversely related to frequency, meaning that as the frequency increases, the wavelength decreases. Formula for Wavelength: The wavelength is calculated using the formula: λ = c / f Half line wavelength = λ/2. Quarter line wavelength = λ/4. Half-line wavelength is used to maintain the distance between two successive elements in an antenna array. Where: λ is the wavelength. c is the speed of light (approximately 299,792,458 meters per second). f is the frequency . The calculator below will pr...

A charge Q1=-20 uC is isolated at P (-6, 4, 6) and charge Q)= -50 pC is  located at R (5, 8,-2) in a free space. Find the force exerted on Q2 by QI  in vector form. The distance is given in meters. Verify the answer using  MATLAB. Matlab Code: q1 = 20e-6 q2 = 50e-6 r1 = [5 8 -2] r2 = [-6 4 6] a = norm(r2-r1) unit = (r2-r1)/a b = a^2 f = (q1*q2)/(4*3.14*8.854e-12*b)*unit F = norm(f)
