There's a long conductor carrying a 60 hz AC current. There's a second conductor parallel to the first current carrying conductor, and a hundred meters away from it.
I want to know what the electric potential induced by the changing B field is in the second conductor.
Theoretically I could...
dV/dx=E
E*q=F=m*a
dq/dt=I
v/R=I
Say you have a situation where you have a constant DC current in a conductor. Applying the above equations to this situations seems to lead to a contradiction, so I’m confused.
-So if you have constant DC current then that indicates dq/dt is a constant
-If dq/dt...
Hi,
Say you have a two conductor transmission line in TEM mode. The E and B field's will look something like the picture below with the E field in blue and the B field in red.
The E field should point in the direction of the current, as it's what makes the charges move. The E field in the...
I’m confused:
Long distance electric power lines are modeled with distributed impedance and are therefore modeled as transmission lines.
Long distance electric power lines are considered to be a two wire line (for a single phase of the electric power line anyway). What other types of...
Any function of the form f(x+ct) or f(x-ct) can be a solution to a wave equation - including the electromagnetic wave equation generated by combining maxwell's equations. Light is an electromagnetic wave which obeys maxwell's equations.
If you were to meausure the electric field of light, is it...
