12. THVENIN AND NORTON EQUIVALENT CIRCUITS
(textbook 2.6)
These equivalent circuits are used to simplify complex circuits consisting of
resistances and sources. Using these equivalents is common, for example,
in complex electrical circuits consisting of m

TRANSIENT ANALYSIS
(textbook 4.1-4.3)
In this part, we consider circuits consisting in capacitors and inductors in
addition to elements we looked at before. Capacitors and inductors respond
to time-varying currents and voltages, so here we consider time-d

1. CIRCUITS, CURRENTS AND VOLTAGES
(textbook 1.2)
An electrical circuit consists of various types of circuit elements connected
in closed path by conductors.
Circuit elements can be resistances, inductances, capacitances, voltage
sources, etc.
EXAMPLE: Ca

9. VOLTAGE-DIVIDER AND CURRENT-DIVIDER CIRCUITS
(textbook 2.3)
Voltage Division Principle.
When we apply voltage to a series of resistances, a fraction of that voltage
that drops across each of them is the ratio of given resistance to total
series resista

11. MESH-CURRENT ANALYSIS
(textbook 2.5)
Besides node-voltage analysis, mesh-current analysis is another general
analysis technique that can be applied to planar circuits circuits that can
be drawn without conductors or elements crossing each other.

CAPACITORS AND INDUCTORS
(textbook 3.1-3.5)
Capacitors and inductors are energy storage elements they can store
charge and return it back into the circuit.
Capacitors and inductors are passive elements like resistors. They do not
generate energy they just

5. CIRCUIT ELEMENTS
(textbook 1.6)
Now we start learning about circuit elements.
i) Conductors.
Ideal conductors have zero resistance. The voltage between the ends of an
ideal conductor is zero no matter what current flows through and how long
or narrow c

13. OPERATIONAL AMPLIFIERS
(textbook 14.1-14.3)
Operational amplifiers (op amps) are integrated circuits used to transform
electric signal (amplify the voltage).
They normally consist of tens of transistors, resistors and capacitors
integrated in one circ

An electric circuit is a closed loop of circuit devices interconnected by conducting material. Figure 2.1 symbolically shows a Power Supply (PS) and a
Resistor (R) connected by conducting wire. The PS provides the power to
drive electric charge around the

: Measuring Voltage and Current
-Push the button on the multimeter labeled DCV so that the multimeter
will measure DC volts.
Verify that the voltage between the red & black terminals at the bottom left
of the console is 15 volts DC (+/-). (The switch must

: Measuring Meter Loading
Ideally an ammeter has zero resistance so that when current flows through
it the voltage across it is zero. However, a real ammeter has a small
resistance and therefore a small voltage when current flows through it.
Determine Amm

Practical
Obtain a lab kit which contains resistors, wires, the circuit board and an
analog meter. You will also use the 4 digit multimeter, the +/- 15V power
supply in the bottom left and the DC power supply mounted on the right of
your workstation.
Ex.

Resistor bands.
For example, a resistor having 4 bands coloured red-violet-orange-gold has
a resistance of 27,000 with a tolerance of 5%.
Power: Power P is the rate of energy supplied or consumed by a device in
a circuit and is defined as P = V I with uni

the resistors in series, or parallel?). There are many resistors available for
