  物理电磁学常见公式

  Electric Fields and Forces Formulas

  Coulomb&aposs Law: F = k·q1·q1/r2

  DC Circuits Formulas

  Ohm&aposs Law: V = I·R

  Power dissipated in a resistor: P = I·V = V2/R = R·I2

  Resistance: R = ρ·l/A

  Equivalent resistance of series resistors: Rs = R1 + R2 +...

  Equivalent resistance of parallel resistors: 1/Rp = 1/R1 + 1/R2 +...

  Equivalent capacitance of series capacitors: 1/Cs = 1/C1 + 1/C2 +...

  Equivalent capacitance of parallel capacitors: Cp = C1 + C2 +...

  Electric field of a charge q: E = k·q/r2

  Work done by electric field: W = q·E·d

  Electric field between two metallic plates: E = V/d

  Magnetic Fields and Forces Formulas

  Magnetic force on a moving charge: F = q(v x B) = q·v·B·sin(θ)

  Magnetic force on a current carrying wire: F = I·l·B·sin(θ)

  Magnetic field created by a current: B = (μo/2π)·(I/r)

  Faraday&aposs Law: E = -dΦ/dt
