Physics I Name:
__________________________________________
Electric Current
and Circuits
Study Guidelines
Describe the flow
of electric charge.
Describe what
is happening inside a current-carrying wire.
Give examples
of voltage sources that can maintain a potential difference
in a circuit.
Describe the factors
that affect the resistance of a wire.
Describe Ohm’s
Law
Explain the causes
of electric shock.
Distinguish between
DC and AC and describe how AC is converted to DC.
Compare the drift
speed of conduction electrons in a current-carrying wire
to the signal speed of changes in current.
Compare the motion
of electrons in a wire carrying AC to the flow of energy
through the wire.
Relate the electric
power used by a device to current and voltage.
Describe the configuration
of a working circuit.
Distinguish between
series and parallel circuits.
Describe the characteristics
of series connections and of parallel connections.
Interpret circuit
diagrams.
Determine the
equivalent resistance of circuits having two or more resistors.
Explain the cause
and prevention of overloading household circuits.
State Standards Addressed:
P.1.18
Explain
the concepts of electrical charge, electrical
current, electrical potential, electric field,
and magnetic field. Use the definitions of the
coulomb, the ampere, the volt, the volt/meter,
and the tesla.
P.1.19
Analyze simple arrangements
of electrical components in series and parallel
circuits. Know that any resistive element in a
DC circuit dissipates energy, which heats the
resistor. Calculate the power (rate of energy
dissipation), using the formula Power = IV = I2R.

1. Why do
some materials begin to superconduct at very low temperatures?
Present your findings to the class in the form of a report,
poster, or presentation.
2. Tantalum
is widely used in electrolytic capacitors. Research
tantalum, its properties and how it is used. Present
your findings to the class in the form of a report, poster,
or presentation.
3. Unlike
pure electric vehicles, Hybrid Electric Vehicles still
burn gasoline in combustion engines. Do you think
the increase in fuel economy and the reduced emissions
of HEVs go far enough to address the problems at hand?
- Present your findings to the class in the form of a
report, poster, or presentation.
4. Research
hydrogen fuel cell technology. Use the following
questions to guide your research: How do fuel cells
work? Do they produce any harmful emissions?
In what form is the hydrogen stored? What are some
possible sources of hydrogen fuel? What problems
must be solved before hydrogen fuel cells are ready for
widespread use? -Present your findings to the class in
the form of a report, poster, or presentation.
