Study of LR Circuit with a source of Alternating EMF with power supply and 4 meters

Order Code: 36209

SPECIFICATION

Experimental Training Board has been designed specifically for the study of L-R circuit with a source of alternating E.M.F. The board is absolutely self contained and requires no other apparatus.
Practical experience on this board carries great educative value for Science and Engineering Students.

Object:
To study L-R circuit with a source of alternating E.M.F. and thus to determine :
01. The power factor, cos f of the inductive load.
02. The equivalent power loss resistance of the inductor.
03. The inductance of the inductor.
04. The phase difference between applied voltage and that across resistance.

Features:
The board consists of following built-in parts :
01. Mains transformer having secondary tappings at 20V, 30V, 40V, 50V & 60V at 500mA.
02. Two A.C. Voltmeters, 65mm round dial to read 0-50V.
03. A.C. Voltmeter, 65mm round dial to read 0-75V.
04. A.C. Milliammeter, 65mm round dial to read 0-500mA.
05. One inductor of which inductance & resistance has to be measured.
06. One high wattage resistance.
07. Mains ON/OFF switch, Fuse and Jewel light.
* The unit is operative on 230V ±10% at 50Hz A.C. Mains.
* Adequate no. of patch cords stackable from rear both ends 4mm spring loaded plug length ½ metre.
* Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections /observation of waveforms.
* Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References.
* Weight : 3 Kg. (Approx.)
* Dimension : W 340 x H 110 x D 210
