Question 2 Suppose that there is a spherical capacitor with inner radius a and outer radius b. a) Find the capacitance of this conductor in terms of a and b. b) When the outer radius b goes to infinity, show that C= 4 nE, a, c) While you are cheging the capacitor, infinitesimal small charges is moved from one plate to other one under potential difference V(t) at any time. Thet charge is called as dq(t), and we move this charge from a to b in time

1.Based on the mathematical equation for the potential difference across a charging capacitoras a function of time, how long does it take a capacitor to become fully charged? Why?2. From a practical point of view, how many time constants are required for a capacitor tobecome fully discharged (i.e. more than 99% of the charge lost)? Why?

Q1) Coaxial cable with length of 20m, along z axis, with a-2mm, b-4mm, c-5mm as shown in cross section figure. The space between a and b is filled by dielectric material with €r = 5. Find: 1) the capacitance of this cable. 2) the capacitance of a portion of this cable bounded by 0 <Ø<180°, L=20m.

Three copocitocs ore connected as shown in the figure. Ihe Capacitors all have +he some dielectric material and The above Copacitonce Values include the dielectric effect, 2UF a CE a What is the equivalent copacitonce between a ond 6? 6, If there is a voltoge of 1ov between a ond b. what is the charge on the 2 UF capacitor? C. For case (b), what is the Voltage across the 4uF Capacitor? d. Suppose now we take the 4e F copacitor from where it is ond put all three capacitors in series. Because of the dielectrics used, each copacitor will break down if the potentia) exceeds 60 V. What is the maxinum Voltage that Can be applied across a ond b in this case without breaking down ony of the Capacitors?
