Lab Instruments & Supplies By Labworld

• A rheostat is a variable resistor which is used to control current.They are able to vary the resistance in a electric circuit without interruption.
• It is an air cooled tube type rehostat with slider for varying the resistance upto 100 ohms with current carrying capacity of 1 ampere..It has an wire winding on the ceramic tube.
• size 6 inches tube type
• Porcelain tube

• On base Copper coil of heavy gauge with two terminals for positive and negative supply
• It works well with 3 amp dc power supply at 6-12 volts
• Use this Air Core to provide an external magnetic field where required and to change the rate of magnetic flux passing through a coil. It consists of a plastic spool with windings of insulated copper. It is useful for classroom experiments and demonstrations on magnetic fields.
• It is used as instrument apparatus for students,schools and laboratory.connect a power supply that does not put out more than 5 amps to the solenoid, with the positive lead at one terminal and the negative lead at the other terminal. The coil will generate a magnetic field when current passes through it. By using a compass, iron rod, or iron filings, students can study the nature of the electric field generated by this simple electromagnet.
• Includes air core solenoid and Iron rod 8mm thick

• Rheostat 40 ohms resistance and 1.2 amperes current capacity
• Metal foot,Brass Terminals,Phosphorus slider and Brass rod
• size 8 inches long tube type
• Porcelain tube and good quality wire
• Make in India product export quality.

• It is a basic electric switch with two terminals for circuit to use in physics lab experiment
• Strong base of pvc with rust resistance terminals and one plug key for making or breaking the circuit
• Plug key completes the circuit for current to flow and when it is removed circuit breaks
