  下面为大家整理的是关于SAT2物理公式的总结,重点放在了电磁学方面。掌握SAT2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。

  物理电磁学常见公式

  Electric Fields and Forces Formulas

  Coulomb&aposs 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&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 +...

  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

  以上就是这三类SAT2物理学公式的全部内容,非常简洁,只包括了公式的本身内容。大家如果想要更加了解相关的公式应用情况,一定要重新复习一下自己的高中物理,然后更加有针对性的练习SAT2物理考试的题目。
