Measurement of unknown resistance using Kelvin's double bridge.
Reference: Pragna
Measurement of unknown resistance using Wheatstone bridge.
The bridge trainer kit consists of:
a) DC power supply - 5V/1A.
b) MR-100 sensitive galvanometer.
c) 2 ten turn potentiometers with dial to vary fixed resistance.
d) The ratio arm consists of rotary switch of 7 multiplying factors of 0.001, 0.01, 0.1, 1, 10, 100 and 1000.
e) 230V AC mains operation.
