Temp. of a torch bulb filament by its resistance measurement with Power Supply and 2 digital meters (C.R.)

Order Code: 36282

SPECIFICATION

Experimental Training Board has been designed specifically for obtaining the temperature of a torch bulb filament by its resistance measurements. 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 determine the temperature of a torch bulb filament by its resistance measurements.

Features
The board consists of the following built-in parts :

0-6V D.C. at 2A, I.C. regulated continuously variable and short circuit protected power supply, with coarse and fine voltage control.
Two Digital Panel Meters (for measurement of D.C. voltage and current).
