Demonstration: An electric current transfers energy.
Practical Activity 14-16
Demonstration: Simple demonstrations to stimulate discussion about the different ways in which energy can be stored...
Demonstration: The simple pendulum used as a stimulus to discuss changes in the ways that energy is stored.
When an electric current passes through a long, hollow coil of wire there will be a strong magnetic field inside the coil and...
Teaching Guidance 14-16
Many textbooks and teaching schemes talk of ‘transforming’ energy, or of ‘converting energy from one form to another’. This is...
Here you can show that there are such things as compensated circuits: that is, two circuits where the character of the...
Classroom Activity 14-16
In this activity the power input to the wind stream driving a wind turbine is compared with the power delivered to an external...
This is an interactive teacher demonstration that can be used to explore and to get students talking about various aspects of...
Use this set-up to introduce the motor effect: a motor's spinning comes about from the interaction between the current in a...
The energy shifted every second in this circuit depends on both the current and the potential difference. In this simple...
Physics Narrative 14-16
Batteries are just about everywhere. Expensive, portable power is something that we are prepared to pay for. Mobile phones...
Controlling the rate at which energy is shifting (the power) has been, and remains, a central concern of technology. Directing...
