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 118: Potential Dividers

Produced by the Institute of Physics, this student experiment introduces the use of a potential divider as a source of variable potential difference. Students also learn to use potential dividers to detect temperature or light levels.

Episode 119: Preparation for EMF and Internal Resistance Topic

This series of activities, from the Institute of Physics, explores electromotive force (emf), internal resistance, voltage, current and charge. They link with a general discussion of energy transfers within electric circuits, involving energy transfer from a chemical battery to electrical work. Each learning...

Episode 120: Energy Transfer in Electric Circuits

Produced by the Institute of Physics, this learning episode can be used to revises the idea of electromotive force (emf), introduce internal resistance and the consequent energy losses.

The activities include:
