Study guide for the First Exam
EE 302
Dr. Bruce McCann
1.
Physical basics: Know the definition and understand the units for charge, voltage, current, power,
work, energy and resistance.
You must really understand these fundamental concepts and how they
interrelate.
2.
Know the unit prefixes micro (
μ
), milli (m), kilo (k) and mega (M).
You do not need to know the
others (for now).
Remember to put units on all numeric answers.
3.
Understand ideal voltage and current sources, short circuits, open circuits and switches.
4.
Be able to compute the power absorbed or delivered by a component.
Be able to identify which
components in a circuit absorb power and which deliver power.
Be able to demonstrate power balance
in a circuit.
5.
Know Kirchhoff’s Laws and how to apply them.
Understand reference directions for current and
voltage.
Be sure you know how to use signs in a selfconsistent manor when writing the equations for
the currents at a node or the voltages around a loop.
6.
Know Ohm’s Law in all its forms.
Be sure you know how to use reference directions in a self
consistent manor when writing the equations for the voltage and current for a resistor.
Remember that
Power = I

R or V

/R and know when and how to apply these shortcut formulas (V and I must be the
voltage and current associated with the resistor, R).
Understand the importance of the power rating of
