Okay.Let me introduce myself.I am a first year undergrad CS student who has to study basic electronic course for one semester.As the title says,I am really falling behind in the course.Believe me,My lecturer doesn't teaches anything properly.She just write the horrifying formulae on the board...
I have having some serious doubts in clamper circuits.
For example,let me take the example of a +ve clamper circuit.

The diode I am considering is an ideal one.In the notes,it is written that during the negative half cycle of the A.C...
Please Help.
I am not getting the concept of ripple factor in half wave rectification with the help of diode.The derivation done by our lecturer is not clear.Someone please explain the concept and its derivation.
Also it seems from the derivation given by our lecturer that there are two types...
Have you read anything about the concept of potential energy of a spring?This question is directly based on that..
The kinetic energy of the train is being converted in the potential energy of spring?
Thank you writing out such a thoughtful post.By watching the youtube videos,I have understood conformational isomerism by myself.But the main problem is configurational isomerism.Especially the questions which ask which molecule has which axis of rotation(C-1 or C-2 or C-3..)?.How many planes...
Currently,I am studying the topic Isomerism in Organic chemistry and Guess what?.I suck at it. My Imagination power is kinda weak so I am having a really hard time in understanding Steriochemistry.Believe me I really try my best but still unable to fully understand it.
My teacher doesn't use any...
Ah..you made a mistake..a=change in velocity/time taken
the direction of ball changes after rebound so change in velocity=(18-(-23))
And acceleration=(40)/0.0033
and also don't worry about the magnitude of acceleration.The force acting on the soccer will be impulsive(have very large value) so...
You should know that whenever mass is ejected from system,it applies a force whose magnitude is equal to=(dm/dt*v)
v=Relative velocity of ejected part will respect to system.Here v=0..So no force will apply on system when the sand is draining although mass of system will continuously decrease...
The object will fall with terminal velocity when the gravitational force and the drag force become equal.
ie. mg=k*v^2
Now we know the terminal velocity
At any instant of time
F(net)=mg-kv^2
m.a(net)=mg-kv^2
m.v.(dv/ds)=mg -kv^2 (accn=v. dv/ds)
now integrate the above eqn using proper limits
I really appreciate your experimental approach but you need to study a bit more to do it properly..When the cylinder rotate,the equation of the acceleration are quite complex.So don't bother about it..My suggestion would be to take a small point object and experimentally determine the time...
You can only find it out by doing experiments if you beforehand don't know it..Make you clear that the cylinder does slide here .We have only assumed that the cylinder is not rotating..
Have you read Laws of Motion?IF not,then leave it.
