→ fridayjason:因疊加原理 跨壓v可為各電源各自造成的總和 10/04 22:50
──+ V2 -──+ V3 -──+ V4 -─
│ │ V1=10, V2=20cos20t, V3=30sin20t
+ +
V4=50cos40t
V1 v 電阻
- -

────────────────
(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)小題要求啥...跟前兩小題有關嗎???
感謝回答喔 ^^
