Experiments:

• Exp-1 To investigate the equipotential lines of electric fields.
• Exp-2 To draw the equipotential lines for bar electrode.
• Exp-3 To draw the equipotential lines for disc electrode.
• Exp-4 To draw the equipotential lines for ring electrode.

Salient features :

• Multipurpose power supply.
• Point needle for tracing the field line.
• Easy setup and connection.
• Electrical safety tested.

Principle and Working:An equipotential line is a collection of points in space when each point has the same value of electric potential.
In the present setup, a voltage is applied between a pair of electrodes placed in a plastic trough filled with distilled water and voltage is measured at different points with a needle connected to a multimeter. The points are marked on another graph paper with reference to the graph placed under the trough.

Product Details:

Rotation of earth on its axis and moon revolves it every 29.5 ‘days’. It will also show months,seasons and pattern of tides. Demonstration of varying length of day by creating shadows. Identification of the pole star and others from different positions on earth.

Additional subjects to study with the Earth-centred model:

• Day and night
• Shadows and the seasons
• The Moon's month, phases and eclipses
• The Pole Star, circumpolar stars and a nocturnal
• The Moon and stars from different positions on Earth
• The tides
• Space travel.
