Questions
Resistances in the two gaps of a meter bridge are l0 ohm and 30 ohm, respectively. If the resistances are interchanged the balance point shifts by
detailed solution
Correct option is D
S= 100−ll . RInitially, 30 = 100−ll × 10 ⇒ l=25 cmFinally, 10 = 100−ll × 30 ⇒ l=75 cmSo, shift = 50 cm.Talk to our academic expert!
