e ce , rd 0010 what memnum and minum capictance can you fr" tom these, How d?pe, male erneton n each eater You have three capacitors, of capacitance 340o pr. T700 Ma imum Capacitance 2.11e-08 C apacit ance 1.91e-09 F 9 POSE 16 measured to be 41 ?, caculate each of the fol-ng. In the fiqure below, the total resistance is 19 kn, and the battery's emf is 20.0 V. If the time constant (a) the total capacitance of the circut 2 16 after the switch is closed b) the time it takes for the voltage across the resistor to reach s0.0

Explanation / Answer

here,

C1 = 3400 pF

C2 = 7700 pF

C3 = 0.01 uF = 10000 pF

for minimum capacitance , the capacitors are connected in series

1/Cmin = 1/C1 + 1/C2 + 1/C3

1/Cmin = 1/3400 + 1/7700 + 1/10000

solving for Cmin

Cmin = 1908 pF = 1.91 * 10^-9 F

for maximum capacitance , they are connected in parallel,

Cmax = C1 + C2 + C3

Cmax = 3400 + 7700 + 10000 pF

Cmax = 21100 pF = 2.11 * 10^-8 F
