Homework Statement
This problem is to find the I and V by ideal diode model method (assume there is no voltage drop and resistance within the diode)
Homework Equations
Just simple Ohm's Law equation
The Attempt at a Solution
First i assume the diode 2 is open, but i don't know...
sorry , not (b)1 and (b)2,
it should be from relevant equations.
As you said, am i necessary to derive other equations
for this problem?
And then following the method as when light is incident on slits
to derive the equations for this problem?
Homework Statement
A source S of monochromatic light and a detector D are both located in air a distance h above a horizontal plane sheet of glass, and are separated by a horizontal distance x. Waves reaching D directly from S interfere with waves that reflect off the glass. The distance x is...
Since the question quite long and contains many formulas,
so i take a photo instead.
my question is that for part b
since Z= \sqrt{R^2+(X_L-X_C)^2}
can i subst X_L = (W_0+\triangle{\omega})L
and X_C = \frac{1}{(w_0+\triangle{\omega})L}
into the Z= \sqrt{R^2+(X_L-X_C)^2}...
the question is that:
A rectangular loop with width L and a slide wire with mass m are as shown in Fig. A uniform magnetic field \vec B is directed perpendicular to the plane of the loop into the plane of the figure. The slide wire is given an initial speed of v_0 and then released. There is...
i am sorry since i do not familiar that tutorial yet...
Should i integrate \frac{2 I_0}{\pi a^2} [1- (\frac{dr}{a})^2]
from 0 to a? if yes, how to integerate (dr)^2
the question is that:
A long, straight, solid cylinder, oriented with its axis in the z-direction, carries a current whose current density is \vec J. The current density, although symmetrical about the cylinder axis, is not constant but varies according to the relation
(the relation is in...
Is \vec{dF}= \frac{q dQ}{4\pi\epsilon_{0}r^2}\(\vec{i}+\vec{j})
to be integrated directly in terms of vector?
or find the magnitude of \vec{i}+\vec{j} first?
