First-order Circuits
Reading: Sections 2.9, 8.2, 8.3, 8.6 and 8.9.
Objectives: We want to be able to
- recognize first-order circuits.
- determine the initial condition of a first-order circuit.
- determine the time constant of a first-order circuit
- use Thevenin and Norton equivalent circuits to analyze first-order circuits
- express element voltages and currents of first-order circuits as functions of time.
- use the step function to represent a piecewise linear function.
- interpret a plot of voltage or current from a first order circuit.
Lecture Notes:
- A step-by-step procedure for analyzing first-order circuits.
- Worked examples illustrating the step-by-step procedure.

- Source transformations.
- Superposition.
- Thevenin and Norton equivalent circuits.
- Maximum power transfer.
- Op amps
- Ideal op amps.
- Node equations for op amp circuits.
- Standard op amp circuits.
- Circuits containing capacitors and inductors.
- Using the element equations.
- Dc and switched DC circuits.
- Series and parallel combinations.
- First-order circuits.
- Step functions and switches.
- Steady state response and initial conditions.
- Time constants.
- Analysis using Thevenin and Norton equivalent circuits.
- Plots of voltages or currents.
- This midterm exam will be "closed book, closed notes" but I will provide a "crib sheet".
- Bring a calculator.
Practice Exams:
- Practice Exam 1 exam, answers and solutions.
