OBJECT

To measure the power in a single-phase circuit using three Voltmeters.
To measure the power in a single-phase circuit using three Ammeters.

FEATURES

The complete Experimental Set-up consists of the followings :

Moving Iron AC portable : In housed in bakelite case with knife edge pointer & anti parallax mirror scale of 140mm voltmeter / ammeter length, spring controlled movement, having accuracy class 1.0.
- Voltmeter range 0–300 Volt : 3 Nos.
- Ammeter range 0–10 Amp. : 3 Nos.
VARIAC : Variable voltage transformer table/floor mounting with enclosure input 230V, output 0–270V at 8 Amp.
VARIABLE LOAD : Uses 6 heating rods of 50-70E, 750 Watt each, based on cement asbestos sheet of size 7.75 x 23.75 inch, Output are on terminal with connecting series & parallel connections by switches, to obtain different loads 8.33 to 70 ohms app.
FIXED RESISTANCE : In three steps Uses 2 heating rods of 50-70E, 750 Watt each, based on cement asbestos sheet of size 6.75 x 14 inch, Output are on terminal with connecting series & parallel connections by switches, to obtain different resistance 100-140E, 50-70E, 25- 35E app.
