Click For Summary

mA/mV and A/V are equivalent units when considering transconductance parameters, as the milli prefix cancels out. In the example of 6.42mA/26mV, converting mA to A by dividing by 1000 results in A/V. The discussion highlights the importance of understanding unit conversions in electrical engineering. Clarifying these units is essential for accurate calculations in transistor behavior. Overall, the relationship between these units is confirmed through proper dimensional analysis.

Homework Statement

Is mA/mV the same as A/V?

Suppose I have 6.42mA/26mV the milli's cancel out and give A/V?

This is in regards to transconductance parameters for transistors, but it's just a question of units.

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
