What is the common unit of conductivity if the dimensions are expressed in centimeter?
Options
- Acm ⁻¹
- B⁻¹ ~cm ⁻¹
- Ccm
- D⁻¹ ~cm
Correct answer
B. ⁻¹ ~cm ⁻¹
Step-by-step solution
If is a resistivity and is conductivity or specific conductance, then aligned &= 1 ; =R a l & = 1 R a ⁻¹ m⁻¹ (O R ohm ⁻¹ ~m ⁻¹ or S ~m ⁻¹ ) aligned (In C.G.S. system, the units of are ⁻¹ ~cm ⁻¹ or S cm ⁻¹ which are used commonly)
