0Consider a tank which is filled with water and placed at some heights. This tank has a pipe connection that is going downwards to another tank in the ground level. The height difference between the two tanks can be considered as the potential difference (which measures in "voltage" ), and the flow of water from the container 1 to tank two can be regarded as the "current". And the funny part is one day a stone got stuck in halfway of pipe and the water flow reduced, which can be considered as the term "resistance."😀
