a cell can be balanced against 110 cm and 100 cm of potentiometer wire ,respectively with and without being short circuited through a resistance of 10 ohm what is its intrnal resistance? in this type of question how we can know which is L1 ,L2, also solve this question

Expert Answer:

Value of internal resistance = [L1-L2)/L2]*value of the resistance
Hence the value of the resistance = [(110-100)/100]*10 = 1 ohm
Hence the value of the internal resistance is 1 ohm.
