物理九年级电学所有公式以及变形公式和用法,

Answer 1

等一下!

P=UI
=W/t
=I^2 R
=U^2 / R
=Q/t
R=U/I
=P / I^2
=U^2 / P
=R1+R2+……+Rn（串联）
=(R1*R2)/(R1+R2)（并联）
I=U/R
=P/U
=√(P/R)
=W/Ut
=Q/Ut
=√(W/Rt)
=√(Q/Rt)
U=IR
=P/I
=√(PR)
=W/It
=Q/It
=√(WR/t)
=√(QR/t)
W=Pt
=UIt
= I^2 Rt
=( U^2 t)/R
=Q
Q=Pt
=UIt
= I^2 Rt
=( U^2 t)/R
=W
t=W/P
=(UIt)/P
=(Pt)/(UI)
=Q/( I^2 R)
=Q/UI
=Q/P
=W/( I^2 R)
=W/UI
=W/P
