下面小编为大家整理的是关于SAT物理电磁学公式的总结。掌握SAT物理公式是大家解答各类题目的前提条件，不仅仅要记住还要对公式的用法了然于心才可以。一起来看看详细内容吧。

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)
