The way I understand it, thevenin circuit is the equivalent open circuit voltage and the resistance/impedence seen looking in from the terminals.
In this problem to work out your thevenin resistance, you are given the current that flows and the voltage across the terminals when the circuit is...
If I convert to the frequency domain and have my voltage as my zero phase reference it shouldn't matter should it? ie voltage 7.071 V @ 0degrees
I thought what I tried was mesh loop analysis.
ot sure if this helps or hinders.
But there is Wien's Law that allows you to determine Peak wavelength for a given temperature in Kevin
ie
\lambda _{peak} T = 2.90 \times 10^{ - 3} meters.Kelvin
The energy gap is the energy required by a semiconductor needed before starting to...

Sorry I do realise the units should be in Coulombs I just in autopilot when I was typing units in sorry.
As far as the Areas goes, that what I thought initially aswell.
When I calculated the surface area initially I did so for a cube.
Thus 6x^2 where x was side dimension of cube. ie the...

Should I than from finding vector <1, -2, 1> do the cross product of it and the direction vector of the line <3,2-1> and than try and find the Cartesian equation of plane ?
Homework Statement
Question states "The plane that contains the line r=<-2,4,3>+t<3,2-1> and is perpendicular to the plane r=<5,0,0>+s<2,1,0>+t<-1,0,1> is:"

Homework Statement
It seems to be obvious. But would like to check that for a line to be contained in a plane it needs to be parallel. Correct?

The Attempt at a Solution
I still haven't been able to do this.
I tried to do with cross product of <0,1,2> x <-1,2,1>
to get vector normal , which was <-3,-2,1>
than did <-3,-2,1> . < x- (-1), y-2, z-1 >=0
which worked out to be -3x-2y+z=0 however this is not the answer still.

I had worked out the inductance values of components for the known frequency of 50Hz howerver I'm unsure what you mean by "write Z1, Z2 and Z1//Z2 as functions of the known values of resistance, and inductance capacitance and the unknonwn value of frequency".
Homework Statement
AC circuit Vs is 100V 50Hz and is used as reference.
there are two impedences in parallel, made up of a 5ohm resistor and an inductor reactance = +j2 ohm that is parallel with 3 ohm resistor and a inductor reactance = -j3 ohm (though I though negative imaginary part was for...
