Question

(x-1/4m0 = 8.99 x 109 N·m 2/C2) A) 4.7 B) 5.1 C 4.0 D) 4.3 7) A 1.0 m long piece of coaxial cable has a wire with a radius of 1.1 mm and a concentric 7) conductor with inner radius 1.3 mm. The area between the cable and the conductor is filled with a dielectric. If the voltage drop across the capacitor is 6000 V when the line charge density is 8.8 C/m, find the value of the dielectric constant. (k = 1/40-8.998 109 N·m2/C2) A) 5.3 B) 5.7 0 4.4 D) 4.8 8) Three capacitors are connected as shown in the figure. What is the equivalent 8) capacitance between points a and b? 2.0 F 6.0 A) 4.0 F B) 8.0 F 97.1 F E) 1.7 F

Explanation / Answer

7) Option C) is correct.

8) 4.0 uF and 6.0 uF capacitors are in parallel =====> 4 + 6 = 10 uF

Then this 10 uF and 2.0 uF capacitors are in series

Equivalent capacitance = C = 10*2/(10 + 2) = 20/12 = 1.7 uF (Option E)
