define conductance . Give it's unit
Answers
Answer:
CONDUCTANCE:
Electrical conductance, G, is the reciprocal of resistance (R): G=1R. Electrical conductance measures how easily electricity flows through electrical components for a given voltage difference.
UNIT:
The SI unit of conductance is siemens (the older unit was the mho).
Answer:
Conductance is an expression of the ease with which electric current flows through materials like metals and nonmetals. In equations, an uppercase letter G symbolizes conductance. The standard unit of conductance is siemens (S), formerly known as mho.
Conductance is essentially a property found in good conductors of electricity, like aluminum and copper. Atoms and molecules in metals like these are in a state of random motion, which causes the electrons in the outer shells to move out of orbit and become free electrons. These free electrons can move from atom to atom. Whenever there is a potential difference, they travel from low potential to high potential.
