Read Me: About Labs in Physics 9
This section provides an explanation of what is expected from students in the laboratory portion of Physics 9.
Lab 1: Static Electric Charge
An exploration of the world of static electricity.
- 1.1: Background Material
- 1.2: Activities
Lab 2: Electrostatic Potential
We use measurements of electric potential between two cylindrical conductors to determine the radial dependence of an electric field with cylindrical symmetry.
- 2.1: Background Material
- 2.2: Activities
Lab 3: Capacitors
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.
- 3.1: Background Material
- 3.2: Activities
Lab 4: DC Circuits
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.
- 4.1: Background Material
- 4.2: Activities
Lab 5: RC Circuits
We have a look at the time evolution of a circuit where the charge on a capacitor is drained-off through a resistor.
- 5.1: Background Material
- 5.2: Activities
Lab 6: Engineering with Magnetism
We build a rudimentary electric motor and a working speaker.
- 6.1: Background Material
- 6.2: Activities
Lab 7: Electromagnetic Induction
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.
- 7.1: Background Material
- 7.2: Activities
Lab 8: Inductance
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.
- 8.1: Background Material
- 8.2: Activities
Back Matter

Thumbnail: Magnetic fields can be visualized with iron filings, that align along the magnetic field direction. Here the magnetic field of a homogeneously magnetized spherical magnet was accurately computed, and the field is shown with simulated randomly placed iron filings. The density of filings is also proportional to the field strength. The field is strongest around the magnetic poles. (CC BY-SA 4.0; Geek3 via Wikipedia)
