Question

Conductance is the reciprocal of:
A) Resistance
B) Capacitance
C) Inductance
D) Charge

Answer 1

Hint: Conductance indicates the conducting power of the object. It depends on the number of ions present. The greater the number of ions, the greater is the conductance.

Complete answer:
Conductance indicates the degree to which the object conducts the electricity. It is denoted by the letter, G.
Units of conductance are mhos or Siemens.
Resistance is defined as the measure of the opposition to the current flow in the electrical circuit, which is exactly opposite to that of the conductance. The unit of resistance is an ohm-meter.
Thus we can say that conductance is the reciprocal of resistance. Mathematically, it is written as
$G = \dfrac{1}{R}$

Hence the correct option is A.

Note: 1. When the temperature increases, the conductivity of the electrolyte increases. Hence we can say that the conductivity of the electrolyte depends on the temperature. Conductivity indicates the ease at which the heat or the charge passes through the material. There are two types of conductivity namely specific conductivity and cation conductivity.
2. The conductance of an electrolyte also depends on the nature of the electrolyte and the concentration of the solution. The strong electrolytes will have high conductance and likewise, the weak electrolyte will have low conductance.
3. Conductivity was invented by a scientist, Stephen Gray. He is well known as the ‘father’ of electricity Electrical conductivity.
4. Resistance depends on the shape of the object, size of the object, and also the material of the object. Also, it is inversely proportional to the cross-section area.
