Question

wheatstone's bridge is used in measuring option (a) high resistance (b) low resistance (c) both high and low resistance (d) potential difference

Answer 1

Wheatstone's bridge is an instrument which is used to determine the unknown resistance R other given resistances.

for example:

R4 is unknown resistance then it can be find from following equation:

R4=R3*(R2/R1)

so it can find both low and high resistances.

hence option C is the correct answer

Answer 2

Answer:

low resistance option B
