An exploration of the world of static electricity.

We use measurements of electric potential between two cylindrical conductors to determine the radial dependence of an electric field with cylindrical symmetry.

We explore properties of capacitance in a static circuit, including the dependence of capacitance on the geometry of the conductors, the energy stored in the electric field, and the effect of the presence of a dielectric.

We use properties of resistors in series and parallel and Kirchhoff's rules to analyze DC networks, including power supplied by a battery and emitted by light bulbs.

We have a look at the time evolution of a circuit where the charge on a capacitor is drained-off through a resistor.

We bring together tools we have learned from mechanics, magnetism, and graphical data analysis to compute the Earth's magnetic field strength, using a very simple apparatus.

We examine Faraday's law using a coil through which we pass a time-varying current (producing a time-varying magnetic field), and a second coaxial coil in which we measure the induced emf.

We measure the voltage as a function of time through an inductor in a circuit with resistance, and use a best-fit graph to determine its inductance.

This section provides an explanation of what is expected from students in the laboratory portion of Physics 9.
