Unit 4: Electricity
Electricity is familiar to us all, and yet quite mysterious. Is it possible
to actually see electricity? In this unit we will look at the fundamentals of
current electricity and circuits. Some of this may have been touched in
on Grade 9.

SPH 3U1 Electricity Assignments:
- Scientists: Due Date: _______________
Choose SIX scientists who made a contribution to our knowledge of electricity.
Write down one way in which they contributed to science (electricity or electromagnetism),
and one fact about their personal life. i.e. You can have just 2 sentences
about each person.
(12 marks)
- Batteries and Cells (see lesson 4) Due Date: _______________
- Circuit problem set handed out. Due Date: _______________
- Production of Electricity Due Date: _______________
List at least 7 ways of producing (current) electricity, especially commercial
generation of electricity.
Describe how electricity is produced in each case. Don’t write down "electrical
generator", describe what turns the generator.
List at least one advantage and one disadvantage of each method of producing
electricity.
MARKS: 5 marks for each method (however many you come up with). Out of 35
marks.
DUE: day of unit test.
?? alternatively - assign poster project.

Physics1: Electricity Objectives (or Outcomes)
By the end of this unit the student will be able to
define and describe the concepts and units related to electricity and magnetism
(e.g., electric charge, electric current, electric potential, electron flow,
magnetic field, electromagnetic induction, energy, power, kilowatt-hour)
describe the two conventions used to denote the direction of movement of electric
charge in an electric circuit: (i) conventional electric current [movement of
positive charge] and (ii) electron flow [movement of negative charge])
[Most of the following set of electricity objectives are also covered in
grade 9 science]
relate current and voltage
for a resistor (Ohm’s law)
describe how the resistance
of a wire depends on its length and cross sectional area
apply the relationships for
the rate of heat production in a resistor
identify on a circuit diagram
whether resistors are in series or parallel
determine ratios of voltages
(currents) across resistors connected in series (parallel)
calculate the equivalent resistance
of two or more resistors connected in series and parallel.
calculate the voltage, current,
(and power dissipation??) for any network of resistors
calculate terminal voltage,
EMF, and internal resistance of a battery with a known current
analyze DC circuits using Ohm’s
law and Kirchoff’s rules
connect and use ammeters and
voltmeters correctly
state whether the internal
resistance of each meter is high or low
read analog voltmeters
and ammeters correctly
