According to Pascal's law, pressure applied to an enclosed fluid is transmitted
A. Undiminished in all directions
B. In direction of flow only
C. Only in downward direction
D. With loss of magnitude
Answer: Option A
Solution (By JKSSB Mock Tests)
Pascal's law: pressure applied to a confined incompressible fluid is transmitted equally and undiminished in all directions. Hydraulic lift, hydraulic brakes work on this principle. P = F₁/A₁ = F₂/A₂.
Explanation:
Voltmeter connected parallel, should draw minimum current, so ideally infinite resistance. Ammeter connected series, ideally zero resistance. Galvanometer moderate. Practical voltmeter has high but finite resistance.
