# ENGINEERING CIRCUIT ANALYSIS 8TH EDITION SOLUTIONS PDF

The book used a clear tone and explain each term as it is introduced. Basic concepts are introduced first then are explained and Clearfield with examples and practice problem in each chapter. Practice problems are included in each chapter where more difficult practice problems are included in the exercise section only. The answers to the selected odd-numbered exercise problems are given. Use of Symbols: The Engineering Circuit Analysis book is using symbolic representation and color printing for a good learning experience. Use of Software: The computer-based software like PSpice and Matlab is used while solving circuit analysis problems.

Find the required x-y coordinates of a nC fourth charge that will produce a zero electric field at the origin. The x and p y coordinates of the nC charge will both be equal in magnitude to 4. The coodinates of the nC charge are then 3. Point charges of 1nC and -2nC are located at 0,0,0 and 1,1,1 , respectively, in free space.

Determine the vector force acting on each charge. Point charges of 50nC each are located at A 1, 0, 0 , B 1, 0, 0 , C 0, 1, 0 , and D 0, 1, 0 in free space. Find the total force on the charge at A. Eight identical point charges of Q C each are located at the corners of a cube of side length a, with one charge at the origin, and with the three nearest charges at a, 0, 0 , 0, a, 0 , and 0, 0, a.

Find an expression for the total vector force on the charge at P a, a, a , assuming free space: The total electric field at P a, a, a that produces a force on the charge there will be the sum of the fields from the other seven charges.

This expression simplifies to the following quadratic: 0. A crude device for measuring charge consists of two small insulating spheres of radius a, one of which is fixed in position.

The other is movable along the x axis, and is subject to a restraining force kx, where k is a spring constant. This will occur at location x for the movable sphere. No further motion is possible, so nothing happens. A nC point charge is located at A 1, 1, 3 in free space.

A charge of -1 nC is located at the origin in free space. What charge must be located at 2,0,0 to cause Ex to be zero at 3,1,1? Now, since the charge is at the origin, we expect to obtain only a radial component of EM. Electrons are in random motion in a fixed region in space. What volume charge density, appropriate for such time durations, should be assigned to that subregion?

A uniform volume charge density of 0. What is the average volume charge density throughout this large region? Each cube will contain the equivalent of one little sphere. Neglecting the little sphere volume, the average density becomes 3. What force per unit length does each line charge exert on the other?

The charges are parallel to the z axis and are separated by 0. What force per unit area does each sheet exert on the other? The superposition integral for the z component of E will be: Z Z " 0. With z at 0. The infinite sheet is obtained by letting a! Determine the electric field strength, E, everywhere on the z axis.
