How similar are water currents and electric currents?

Water currents move In All directions (provided) irrespective of the source ,if a wave generated due to an underwater disturbance or Over the surface,The Resulting currents Are Tend to move in all directions Balanced and equally. read more

2 are in series and the water current, which we show it as I, is the same in each. The whole tube l 1 contains, in number, A 1/A 2 tubes each equivalent to the tube l 2, and the situation is similar to when this number of tubes are set in series and transferring their forces to each other finally exert their forces on the tube l 2 (see Fig.3). read more

If there is current flowing through something (water is something) then there will be a voltage difference along the current path. You can measure the voltage different between points on something (including water) to determine if current is flowing in it. read more
