1章:
Va=(Ra/Ra+Rb)V...utk litar slari
Ia=(Rb/Ra+Rb)I...utk litar brsri
2章:
v=RI v=Ldi/dt v=1/c∫di(t)
Xa=絶対平均値=2Xm/Π
Xe=実効値=Xm/punce 2
3章:
a(t)=root 2 A sin (wt+&)
A=Ae ekuasej&
=Aekuasej&
=Ae<&
impidans----->v=RI [R,Ljw,1/cjw]
amidans------>I=YV[1/R.-j/Lw,Cjw]
4章:
P=IV
(有)効電力=Pa cos &=IVcos &
無効電力=Pr=-Pa sin &
力率=cos &=cos (&v-&i)
err..bleh ke neh?...(~O~);!
