Hello all,
I have a project in which i need to design a small vehicle which is able to carry 4kg for 10 meters. I have took it up to 5kg as the frame and wheels add up too 1kg. So the total weight will be 5kg.
Acceleration isn't a priority, but 0.5 m/s I would be fine with.
The wheel have...
I recently learned about Electric displacement field and capacitors, and I have a question that how was the formula derived shown below (blue circle part)?
Thanks!

A resistance thermometer bridge circuit shown below has a
designed maximum temperature of 150°C, ignoring the effects of
connecting wire resistance. If the connecting loop is 200 m
determine the smallest gauge (swg) of copper wire which must be
used if the indicated maximum...
I am stuck with the concept of linearising the non-linear system...what i thought was...non-linear systems are defined by differential equations which is difficult to solve, hence we linearise them to make the differential equation look like a algebraic equation...am i right ?...or is there...
Hello everyone. I searched this forum but couldn't get a good answer! In my country there are few jobs available as quant but one of the companys that hires them went to my university 5 months ago in a carrer fair. They were looking for a engineer graduate to apply and train as quant.

(Wasn't sure on the right section for plasma physics, I apologise if this is wrong).I'm reading up right now on a plasma surrounded by a tokamak wall, and the assumption of ideal magnetohydrodynamics - which assumes very little internal electrical resistivity and so the plasma can be assumed as...
Is it ideal to pursue a electrical engineering and math major?
Basically, I plan to double major in both subjects to keep possibilities for graduate school and eventually, have options for a career. I.e, a math major will allow me the option for graduate math school and electrical engineering...
If u have conducting spherical which is not hollow. We know from guass law that the outter component is experienced electrical force from the inner component. But why the inner isn't experienced the force from the outter. Please show and proof it in mathemetic and describe in the qualitative...

Hi! I have been trying to understand how a "complicated" circiut can be transformed to show which resistors are connected in series and which are parallel... Sometimes I manage to do it but it's often too hard for me because I can't find any sort of algorithm about it. Could anybody show me...

Calculate the electric field strength within the insulation when the conductor voltage difference is 120v. Also determine the voltage@ which the insulation may break if its dielectric...
[b]1. Two pith balls each have a mass of 1 g. and equal charge. One pith ball is suspended by an insulating thread. The other is brought to 3 cm from the suspended ball. The suspended ball is now hanging with the thread forming an angle of 30 degrees with the vertical. The ball is in equlibrium...
A single stationary electron's magnetic flux caused by it's spin gives it a north and south pole right? does that mean it's north pole would be attracted to the south pole of a hypothetical nearby stationary electron?
how would this attractive force compare to it's electric force of...
