The heating and lighting effects of electric current are well
known to the students from everyday life, and they have already
experimented with filament lamps and utilised their illuminating,
or lighting, effect as a measure of the strength of electric
In this experiment, it is important that they realise that in
all these processes, electrical energy is converted into thermal
energy in the form of heat.
In the evaluation, one of the following themes can be
handled according to the state of knowledge of the students: in the
simplest case, the phenomenon and for a higher
theoretical demand, the energy ballance.
Eel = Q with
Eel = U × I ×
The heat capacity of the glass vessel must be taken into
consideration in the evaluation.
Q = [(cGlass +
cWater) × mWater] × Δ
- No additional cable connections between the building blocks needed - clear arragned and quick setup
- Contact saftey due to puzzle blocks system
- Corrosion-free gold plated contacts
- Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside
How does an immersion heater work?
Set up a circuit with a model of an immersion heater and use it
to convert electrical energy into thermal energy.
