MC.1) A thin nonconducting sphere with radius R is given a positive charge Q. Which of the following
graphs best represents the shape of the potential and magnitude of the electric field as a function of
Chapter 27: Current and Resistance
In this section of the course we will be studying the flow of electric charge, current, in a circuit.
We have already seen electric current when we first discussed electric charge.
The electric current (i) is defined by

Chapter 26: Capacitance and Capacitors
We can store electrical potential energy in device called a capacitor. Sometimes we
think of capacitors as charge storage devices. Capacitors are in every electrical device you own
or use. Capacitors range in size fr
Chapter 29: Magnetic Fields
Magnetism has been known as early as 800BC when people realized that certain stones
could be used to attract bits of iron.
Experiments using magnets have shown the following:
1) EVERY magnet has two poles which we refer to as n
Chapter 28: Electrical Circuits
In this section of the course we will discuss electrical circuits, e.g. what happens when a battery
and one or more resistors are wired together. Soon we will explore circuits that contain not only
resistors but also capaci
Chapter 30: Magnetic Fields Due to Currents
A moving electric charge creates a magnetic field. One of the more practical ways of
generating a large magnetic field (0.1-10 T) is to use a large current flowing through a wire.
The calculation of the magnetic

Chapter 31: Induction and Inductance
In Ch 30 we learned the following about magnetic fields:
a) A magnetic field can exert a force on a current carrying wire
b) If the wire is a closed loop then the magnetic field can exert a torque on the loop.
