9/22/2017 Phys 251 Fall 2017 Name Daily Problem Due Monday September 25, 2017 Show all your work and include units in your answers for full credit You have three capacitors with Ci-80 F, C2 = 40 F, and C3-20 F. (a) What is the equivalent capacitance Ceq of the configuration shown here? Are the capacitors connected in series or in parallel? Ceq (Circle one) series parallel (b) What is the equivalent capacitance Ceg of the configuration shown here? Are the capacitors connected in series or in parallel? (Circle one) series parallel all Please see other sidel

Explanation / Answer

here,

C1 = 80 uF , C2 = 40 uF

C3 = 20 uF

a)

let the capacitance be C

as the capacitors are in series

1/C = 1/C1 + 1/C2 + 1/C3

1/C =1/80 + 1/40 + 1/20

C = 11.4 uF

b)

let the capacitance be C

as the capacitors are in parallel

C = C1 + C2 + C3

C = 80 uF + 40 uF + 20 uF

C = 140 uF
