‘mho’ is the unit of ______ of a substance.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. conductance.
‘Mho’ is the unit of electrical conductance of a substance.
The term "mho" is derived from spelling "ohm" backwards, and it represents the reciprocal of resistance. Conductance measures how easily electric current flows through a substance, and is expressed in siemens (S) in modern terms. One mho (or one siemens) is equal to one reciprocal ohm (1/Ω), indicating the ease with which current passes through the material.
