Introduction - The pressure exerted by a liquid on the base of the container depends on the vertical height of the liquid over it not on the area of cross-section. As one goes deeper in the swimming pool, the pressure on the ear drum is found to increase. A column of mercury exerts more pressure th..

Summary - Pressure at a point in a liquid depends upon the depth and on the density of the liquid. The pressure at any depth in a liquid acts equally in all directions. Liquids always find their own level. Pressure applied at any point in a confined liquid is transmitted equally in all the directio..

Potential difference is a measure of work done in moving a unit charge across a circuit. Current in a circuit is equal to the amount of charge flowing in one second. Therefore, the work done in moving 'Q' charges through a potential difference 'V' in a time 't' is given by Work done = potential dif..
