Can meter bridge be used for finding the resistance of (i) moderate values (ii) high values (iii) low values ? Explain.
Text Solution
Verified by Experts
The meter- bridge is most sensitive when the resistance of all the four arms of the bridge are of the same order. It is so for moderate resistance only. The meter bridge becomes insensitive for too high or too low resistnaces. Moreever, while measuring low resistances, the resistances of the copper strips and connecting wires become comparable to the unknown low resistance and hance cannot be neglected.
