An Electronic generator that generates the high frequency saw tooth waves can be termed as a Time Base Generator.

They are many variations of XY recorders. The emf, for operation of XY
recorders, may not necessarily measure only voltages. The measured emf may be
the output of a transducer that may measure displacement force, pressure, strain,
light intensity or any other physical quantity. Thus with the help of XY recorders
and appropriate transducers, a physical quantity may be plotted against another
physical quantity.

222*2 = 16:1 Multiplexer

A submerged body is in stable equilibrium if the centre of gravity of body lies below the centre of buoyancy.
A submerged body is in unstable equilibrium if the centre of gravity of body lies above the centre of buoyancy.
A submerged body is in neutral equilibrium if the centre of gravity and the centre of buoyancy coincides.

Poise is the unit of Dynamic viscosity.
The unit to measure the viscosity can be denoted in the cgs system of units.
1 Pa.s= 10 Poise
In SI unit system viscosity is measured with the unit called pascal second.
Pascal second can be represented as Pa.s.

A rectangular channel section is the most economical when either the depth of flow is equal to half the bottom width or hydraulic radius is equal to half the depth of flow ie, the ratio is 1:2

Water flow in large sized pipes for large flow rates can be measured using
Venturi meter.
A Venturi meter may also be used to increase the velocity of any type fluid in a pipe at any particular point.
It basically works on the principle of Bernoulli’s Theorem.

when j =1 k = 1 and clk = 1; Q output will toggle as long as CLK is high.Thus the output will be unstable creating a race-around problem with this basic JK circuit. This problem is avoided by ensuring that the clock input is at logic ?1? only for a very short time, or to produce a more sophisticated JK flip-flop circuit called a Master?slave flip-flop.

In P-chanel JFET holes move from source to drain => electrons moves from drain to source.

Through formula…in dc circuit freq is zero

We-know-that Xc=(1/2pif*c)

f=0 therefore Xc=infinity
