In a meter bridge the null point
WebIn a meter bridge experiment, initially the jockey is at null point. Now resistance R 1 and R 2 is interchanged. Shift in the position of jockey is ____cm Moderate Solution Meter bridge works on the principle of wheat stone bridge From diagram R 1 = 2 Ω , R 2 = 3 Ω Initially R 1 R 2 = 2 3 = l 100 − l ⇒ l = 40 cm Now R 2 R 1 = 3 2 = l ' 100 − l '
