### SAND MODEL : CIRCLE AREA AND DEMONSTRATION OF π.

Demonstration model of the formula R = r ² · 3.14. The model is filled with fine sand that fills the one hand the area of the circle and the area of squares. The radius of the circle corresponds to the side length of squares. Made of plastic material.

Approx size : 250x130mm

### SET OF SOLID BODIES (Imported)

9 piece set of solids: 3-sided and 6-sided prism, rectangular prism, cylinder, cone, 3-sided, 4-sided and 6-sided pyramid, sphere; Heights: 150 mm; Diameter of sphere: 100 mm Planes to write on.

### SOLAR CELL CHARACTERISTICS

V-I characteristic of a solar cell can be obtained using this apparatus. The ratio of maximum useful power and ideal power can also be calculated. The maximum useful power is the area of largest rectangle that can be formed under the V-I curve. If the voltage and current corresponding to this largest area are denoted by Vm & Im, then the maximum useful power is Vm x Im. The ratio of useful power to the ideal power is called the fill factor. It consists of solar module, decade resistance box module, lamp source, switch and circuit board.
