ECE 201 Topic List
Concepts:
1. Current in terms of charge (q):
i(t) = ∆q/∆t = dq/dt (also found in ECE 311)
2. Ohm’s Law:
V = I*R (also found in ALL ECE COURSES)
3. Work :– difference in energy = W1 – W2 (also fond in ECE 311)
Voltage = energy divided by charge (W1-W2)/Q
Q = I*t
P = V*I
4. Kirchoff’s Current Law :– at any node in an electrical circuit, the sum of currents flowing into the node is equal to the sum of currents flowing out of the node. (also found in ECE 202, ECE 255)

5. Kirchoff’s Voltage Law: – the sum of the voltages in any closed loop is equivalent to the sum of potential drops in that loop

9. Nodal Analysis :- a method of determining the voltage between nodes in an electrical circuit in terms of the branch current

10. Mesh Analysis :- a method to determine the voltage and currents at various parts of a circuit
11. Superposition theorem:- the response in any branch of a linear circuit having more than one independent source is equivalent to the algebraic sum of the responses caused by each independent source acting alone.

12. Source transformations :- a technique in which independent current sources can be transformed into independent voltage sources (and vice versa)
13. Thevenin’s Theorem:- states any combination of resistors, voltage and current sources can be modeled by a single voltage source and resistor in series
14. Norton’s Theorem:- states any combination of resistors, voltage and current sources can be modeled by a single current source connected in parallel with a resistor
