Some people think that the solution to a coal gas and oil shortages is to switch over to electrisity in other words if we run out of gas and oil we can just swich to electric cars

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.

where is the circuit diagram ?

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
