物理电磁学常见公式

Electric Fields and Forces Formulas
Coulomb's Law: F = k•q1•q1/r2
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
 
DC Circuits Formulas
Ohm's 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 +...
 
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's Law: E = -dΦ/dt
