This is the outline of the last exam this term. It's tough. It almost makes me crazy and sick. I have to stay up tonight to review it and make sense of the complicated circuits.
----------Stick to my gun!!!
Chapter one
1. Current:
2. Voltage:
3. Reference direction: Whenever the reference direction for the current in an element is in the direction of the reference voltage drop across the element, use a positive sign in any expression that relates the voltage to current. Otherwise, use a negative sign.
4. Power: If the power is positive (P>0), power is being delivered to the circuit inside the box. If the power is negative (P<0), power is being extracted from the circuit inside the box.
If the P>0, the element be called load(负载), it’s power absorbed.
If the P<0, the element be called source(电源),it’s power delivered.
Chapter two
1. The independent source:
2. The dependent source:
3. resistance:
4. the ohm’s law:
5. the Kirchhoff’s law(基尔霍夫定律): Kirchhoff’s laws include Kirchhoff’s current law (KCL) and Kirchhoff’s voltage (KVL) law.
The Kirchhoff’s law: The algebraic sum of the currents entering any node is zero.(Σi=0)
The Kirchhoff’s law:
Chapter three
Simple resistive circuits
Chapter four: Techniques of circuit analysis
1. branch-current method
2. node-voltage method(节点电压法)
3. mesh-current method(网孔电流法)

(b) the radian frequency
(c) the phase angle (initial phase j)
The phase relation between two sinusoidal functions
3. The phasor
4. The Passive Circuit Elements in the Frequency Domain
