Experiments with electricity lab instruments
Resistance boxes, rheostats and plug keys build the circuits for Ohm's law and for resistances in series and parallel. The meter bridge, post office box and portable Wheatstone bridge find an unknown resistance and the specific resistance of a wire, and the potentiometer compares the EMF of two cells and finds the internal resistance of a cell. The Hoffman voltameter shows the electrolysis of water, and the circuit boards and lamp kits introduce younger students to simple series and parallel circuits.
For electronics, the apparatus cover the characteristics of PN junction and Zener diodes, the common-emitter characteristics of a transistor, LED, LDR and solar cell characteristics, the energy band gap of a semiconductor, logic gate truth tables and operational amplifier circuits. The subcategory also lists loading rheostats and resistive, inductive and capacitive load banks.
Specification examples
The Resistance Box, Plug Type (EL-EAE-10282) uses a 12 mm or 10 mm thick rectangular brass block and coils of double-covered constantan wire on Bakelite spools; the stated accuracy is plus or minus 0.05% to 0.1% with constantan coils and 0.02% to 0.05% with manganin coils. The Meter Bridge (EL-EAE-10289) has a 24 SWG constantan wire clamped to brass end strips, a 3/4 inch laminated base and nine heavy brass lock terminals, and is supplied with a pencil jockey and connecting lead.
Questions about electrical and electronics apparatus
What is the difference between the plug, dial and electronic resistance boxes?
The plug type (EL-EAE-10282) selects wound constantan or manganin coils with brass plugs, with stated accuracies down to plus or minus 0.02%. The dial type decade box (EL-EAE-10284) sets values on one to four dials and works on AC or DC. The electronic type (EL-EAE-10286) switches resistances with toggle switches and is intended for school laboratory use.
Which rheostats are available?
The constantan (Eureka) wire rheostat covers 0.6 to 8 amperes and the nichrome groove type covers 0.3 to 6.5 amperes. Both have phosphor-bronze double-contact sliders on heat-resistant porcelain tubes with three brass terminals. Rheostats listed by length, from 6 to 12 inches, are also in the product grid.
Can electronic cells replace wet Leclanche and Daniell cells?
They are designed as substitutes. The Electronic Leclanche Cell gives a regulated 1.5 V DC output and the Electronic Daniell Cell a regulated 1.08 V DC output, both through 4 mm sockets with overload and short-circuit protection and without liquid electrolytes.
Which semiconductor experiments does this range support?
Diode, Zener diode, transistor, LED, LDR, solar cell, energy band gap and logic gate apparatus are listed, together with IC and operational amplifier trainers for circuit building.
