One
factor affecting manipulation of liquid drop in this format also
involves the angle of tilt sheet. The tilt sheet in a higher slope
position results in faster movement of the drop along the hydrophobic path. If it is in too high slope, it would not be easy to
control the movement and also the drop will not be easy to stop at
the electrode. The angle would be adjusted to meet the ability in
manipulating the liquid drop. In this experiment, the suitable tile
sheet angle was found to be 501from horizontal plane
