Скачать или смотреть Electrical Systems Overview: Ohm's Law & Kirchhoff's Laws for Resistors, Inductors, and Capacitors

In this video, I break down key concepts of electrical systems for the System Dynamics course, focusing on fundamental laws like Ohm's Law and Kirchhoff's Laws. We’ll dive into how these laws apply to resistors, inductors, and capacitors.

OHM's LAW:
Resistor:
𝑉=𝑅𝑖
𝑖=𝑉/𝑅
Capacitor:
𝑉=1/𝑐 ∫1𝑖𝑑𝑡
𝑖=𝑐 𝑑𝑣/𝑑𝑡
Inductor:
𝑉=𝐿 𝑑𝑖/𝑑𝑡
𝑖=𝐿∫1▒𝑣𝑑𝑡


Impedance in Series:
𝑍_𝑡𝑜𝑡𝑎𝑙=𝑍_1+𝑍_2+𝑍_3

Impedance in Parallel:
1/𝑍_𝑡𝑜𝑡𝑎𝑙 =1/𝑍_1 +1/𝑍_2 +1/𝑍_3



(a) Kirchoff’s current law (KCL)
𝑖_1+𝑖_2=𝑖_3+𝑖_4 (Current in=Current out)
KCL is used for nodal analysis

(b) Kirchhoff's Voltage Law (KVL)
Through any loop, the voltage drop is zero
KVL is used for mesh analysis
