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 104: Drift Velocity

From the Institute of Physics, this learning episode shows that charge carriers in good conductors usually move very slowly. It illustrates the derivation and use of the equation I = nAvq.

A range of activities include:
• viewing the movement of permanganate ions in an electric field
•...

Episode 106: Electrical Power

From the Institute of Physics, in this learning episode, students calculate electrical power and through discussion, review their understanding of: • current • potential difference • electromotive force (emf) • charge • drift velocity Students are reminded of the idea that power is the rate of doing work (or the...

Episode 107: Preparation for Resistance Topic

This series of activities, from the Institute of Physics, help student to understand electrical resistance. What is resistance, how it can be measured, how it arises and what affects it? During the topic, resistance is related to current, voltage, type of material, temperature and light intensity. The electrical...

Episode 108: Resistance

From the Institute of Physics, this learning episode provides a quantitative definition for resistance (R = V / I) which reinforces the qualitative notion that more resistance means less current. It looks at Ohm’s law, describing that this is not the same thing as the definition of resistance.
