Regarding your explanation I ended up with the following equation to be solved. Is this correct or did I get your explanation totally wrong??(btw i forgot the dxdy term at the end of the equation)

I will try to solve the question now with your explanation. Thank you very much!

Dear all, I am stuck with the problem which is given below; In this problem the equilibrium equations of the given functional must be derived in u, v, and w directions from which the boundary terms must be found. I think that i have derived the equilibrium equations( 5 equations), but i...

I've drawn four configurations; 1) two resistors parallel (R1 and R2) with a source voltage of 220 V 2) 1 resistor with a source voltage of 220 V 3) 1 resistor with a source voltage of 220 V 4) two resistors (R1 and R2) in series with a source voltage of 220 V For each of these configurations...

hallo everyone, I have a problem which i can't solve. Does somebody know how to solve this problem?? The question is: A 220 V electric heater has two heating coils which can be switched such that either coil can be used independently or can be connected in series or parallel, yielding a...

So i first calculate the resistance of the cable: R(cable)=(0.0175x10e-6 x 25 m)/1e-6=0.4375 ohm Total resistance is R(cable)+R(resistor)=0.4375+46=46.4375 Now the current in the serie can be calculated: 230/46.4375=4.953 amp So, the voltage across the resistance is 4.953 amp x46 ohm=227.83...

hallo everyone, i have here a simple problem that i cannot solve. This is the problem: A resistor of 46 Ω is connected to the end of a power cable. The voltage a the begin of the cable is 230 V. The length of the cable is 25 m The copper area is 1.0 mm2 The specific resistance of...
