The metal box is double ended so that two sets of students can work independently with the same box and can perform different experiments in labs.
Slide apertures are provided which accommodate color filters for color mixing experiments, blinking plates for when the slide apertures are not in use.
The box is provided with a 12V 24W straight filament lamp fixed at the center of the apparatus while at each end is a sliding grooved frame to carry a convex cylindrical lens together with slit screen &/or filter.
Long clear tracks to triple slit screen, two blank plates for closing side aperture when not in use & 1m of twin flex.
Dimensions 308 x 63 x 115 mm high supplied without lenses, filters or other accessories.
A round resistance coil is a laboratory apparatus used in creating and adjusting electrical resistance.
These coils are commonly used in electrical experiments to measure the between current, voltage, and resistance, also to measure the resistance of other circuit components.
The resistance can be adjusted by changing the length of the wire used or by changing the diameter of the coil.
Rheostat 500ohm 1.2 A is used for a variety of laboratory demonstrations, such as is an adjustable resistor used in applications, require the adjustment of current or the varying of resistance in an electric circuit.
The rheostat can adjust generator characteristics, dim lights, and start or control the speed of motors.
Rheostat is used in a circuit to change the resistance of the circuit, so that the different current values can be obtained.
