evaluate the moment of inertia of a thin rod with axis of rotation at the centre ,if its length is 100cm and its mass is 2.3kg​

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
