──+ V2 -──+ V3 -──+ V4 -─
│ │ V1=10, V2=20cos20t, V3=30sin20t
+ +
V4=50cos40t
V1 v 电阻
- -
│ │
────────────────
(a) For the following network,find the rms value of v.
(b) The average power absorbed by the resistance.
(c) State the condition such that superposition of power holds.
我看不懂(c)小题要求啥...跟前两小题有关吗???
感谢回答喔 ^^
