Teaching Advanced Physics: Electric current
From the Institute of Physics, these resources are split into topics and each topic is subdivided into a number of learning episodes. Each episode represents a coherent section of teaching which is typically one or two lessons. The topics covered include: * Electric current and charge carriers * Electrical resistance, thermistors and LDRs * Series and parallel circuits * Kirchhoff’s laws * Electrical energy and power (direct and alternating current) * EMF and internal resistance * Capacitors, capacitance, energy and discharge * Semiconductor devices

Episode 121: Electromotive Force and Internal Resistance
In this learning episode, from the Institute of Physics, students derive the equation relating electromotive force (emf), terminal potential difference, current and internal resistance. They then tackle questions about the internal resistance of a power supply.
...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:
