Please answer both questions.

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 8) A region of space contains an electric field E -E1 i E2j where E1 and E2 are positive constants. A frame whose corners are located at (x, y, z) 3 (a/2, 0, a/2), (-a/2, 0,-a/2), (a/2, 0,-a/2), and (-a/2, 0, a/2). What is the magnitude of the electric flux through the frame? FIGURE 26-12 72 82 4Q 12V 9V 9) Refer the the circuit in Fig. 26-12 to answer the following: (a) Determine the current in the 7-Q resistor. (b) Determine the current in the 8-Q resistor. (c) Determine the current in the 4-Q resistor.

Explanation / Answer

1.FLUX=E2a^2(normal vector is J)

2.7i1+4(i1+i2)=12

=11i1+4i2=12-----1

8i2+4(i1+i2)=9

=12i2+4i1=9

solving the eqn

i1=0.93amp

i2=0.44amp

current in 7ohm resistance=0.93amp

current in 8ohm resistance=0.44amp

current in 8ohm resistance=0.44amp+0.93amp=1.37amp
