The correct Answer is:
### Step-by-Step Solution 1. **Understanding Conductance**: Conductance is a measure of how easily electricity flows through a material. It is the reciprocal of resistance. 2. **Units of Conductance**: The units of conductance are: - **MHO**: This is the most common unit of conductance and is derived from Ohm, which is the unit of resistance. - **Siemens (S)**: This is the standard unit of conductance in the International System of Units (SI). 1 MHO is equivalent to 1 Siemens. - **Parohm**: This is another term used for MHO, indicating the reciprocal relationship with Ohm. - **Simon**: This is an older term that is sometimes used interchangeably with MHO. 3. **Reciprocal Relationship**: Since conductance (G) is the reciprocal of resistance (R), we can express this relationship mathematically: \[ G = \frac{1}{R} \] This means that if resistance is high, conductance is low, and vice versa. 4. **Conclusion**: Therefore, the units of conductance can be summarized as: - MHO - Siemens (S) - Parohm - Simon 5. **Correct Options**: Based on the above understanding, we can conclude that the correct units of conductance are MHO, Siemens, and Parohm, while Simon is also acceptable in some contexts. ### Final Answer The units of conductance are MHO, Siemens, Parohm, and Simon. ---
