Physics Calculators (Page 18)
Velocity, mechanics, energy, electricity and physics tools.
Gauss's Law Calculator
Compute electric flux Φ = Q/ε₀ and field of a spherical charge.
Larmor Frequency Calculator
Compute Larmor precession frequency f = γB/(2π).
Kirchhoff's Voltage Law Calculator
Compute currents and voltage drops in a series circuit (KVL).
Wheatstone Bridge Calculator
Enter four resistances and input voltage to compute the balanced unknown R_x=R₂R₃/R₁ and the output voltage V_out=V_in·(R_x/(R_x+R₃)−R₂/(R₁+R₂)). R₁=100,R₂=200,R₃=100,R_x=200 → balanced, V_out=0.
RLC AC Impedance Calculator
Enter resistance, inductance, capacitance and frequency to compute inductive reactance X_L=2πfL, capacitive reactance X_C=1/(2πfC), impedance Z, phase angle and resonance frequency. R=100Ω, L=0.1H, C=10μF, f=50Hz → Z≈304.5Ω.
Planck Radiation Calculator
Enter temperature to compute the total radiance and peak wavelength via the Stefan–Boltzmann law and Wien's displacement law.
Magnetic Dipole Moment Calculator
Enter turns, current and area (with field angle) to compute the magnetic dipole moment m = N·I·A, its torque and potential energy.
Electric Dipole Field Calculator
Compute axial and equatorial E-field of a dipole p = q·d.
Debye Length Calculator
Compute the Debye length λ_D of a plasma/electrolyte.
Plasma Frequency Calculator
Enter electron number density and mass to compute the plasma (Langmuir) frequency ω_p = √(n·e²/(ε₀·m_e)).
EM Wave Energy Calculator
Enter electric/magnetic field of an electromagnetic wave to compute energy densities and the Poynting vector (intensity).
Skin Depth Calculator
Enter frequency, relative permeability and conductivity to compute skin depth δ=√(2/(ω·μ·σ)). f=60 Hz, Cu (μr=1, σ=5.96e7) → δ≈8.5 mm; f=1 MHz → δ≈66 μm.
