Interpretation:
The internal resistance of the meter if the relative error in the measurement is to be less than
Concept introduction:
Internal resistance is the property of the material by virtue of which the object is able to hinder or obstruct the flow of the electrons that pass through the conductor.When current is delivered by any power source, the voltage available at the output of the system is always lower than that of the voltage at no-load conditions. This reduction in the voltage at the output is caused by the internal resistance.

- The resistance of a 0.008 mol dm-³ solution of NaCl (aq) at 300 K was found to be 2.75 x 10³ . In a separate experiment, using the same conductivity cell, the resistance for a 0.1 mol dm-³ KCI aqueous solution was determined as 125.6 Q. Given that the conductivity of 0.1 mol dm-³ KCl aqueous solution at 300 K is 0.01302 S cm-1, calculate the molar conductivity of the NaCl aqueous solution.arrow_forwardThe resistance of a decinormal solution of a salt occupying a volume between Pt electrodes is 1.80 cm apart and 5.4 cm2 in area was found to be 32 ohms.

- The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. When a kV voltage of 64.6 V is put across the plates of such a capacitor an electric field strength of 3.4 is measured. Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol.
