这是我自己总结的.
P=UI
=W/t
=I^2R
=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^2Rt
=(U^2t)/R
=Q
Q=Pt
=UIt
=I^2Rt
=(U^2t)/R
=W
t=W/P
=(UIt)/P
=(Pt)/(UI)
=Q/(I^2R)
=Q/UI
=Q/P
=W/(I^2R)
=W/UI
=W/P
