Why is the meter bridge method considered unsuitable for the measurement of very low resistances ?
Text Solution
Verified by Experts
While measuring a vary low resistnace using meter bridge,all other resistances used should have low values in order to ensure sensitivity of the bridge. This requires the galvanometer should also be of very low resistances and a very sensitive. Then the end resistances and resistances of the connecting wires used in metre bridge bacoem comparable with the resistance to be measured. This would introduce error in the result. Due to it, the measurement will not be accurate.
