SUMMARY

The discussion centers on the transformer equation V1/V2=N1/N2, which indicates that there should be no current flowing in the circuit under certain conditions. Participants clarify that the presence of a battery connected to the primary coil is crucial for understanding the current behavior. The confusion arises from the assumption that the equation implies a current of zero, which is incorrect when a battery is involved.

PREREQUISITES

The Attempt at a Solution

V1/V2=N1/N2, that means there shouldn't be a current. Why it is 0?
Thanks!

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?
