Episode 122: Using an Oscilloscope
This demonstration or student practical activity, from the Institute of Physics, helps students learn to use an oscilloscope to measure voltages. It helps students to understand the use of a cathode ray oscilloscope by showing:
• how the oscilloscope plots a graph...
Episode 123: Alternating Current
Produced by the Institute of Physics, this learning episode helps students to distinguish alternating from direct currents before revising why alternating current (ac) is so important.
The range of activities include...
Episode 124: Preparation for Capacitors Topic
In this series of learning episodes from the Institute of Physics, students undertake a range of practical investigations into capacitors and their properties. Students apply exponential equations, which can help to reinforce other areas such as radioactive decay.
The topics covered are:

Episode 130: R-C Circuits and Other Systems
From the Institute of Physics, this learning episode looks at energy stored in capacitors and springs as well as the comparison between radioactive decay and a capacitor's discharge. It allows students to explore the concepts of energy storage and exponential decrease...
Episode 1: The Full Spectrum
In this first episode Rebecca Barnes sets the scene for this vodcast series by looking at why we need to send telescopes into space and considers what these 'eyes in the skies' can tell us about the extraordinary Universe in which we live.
