Question

21.66- RC Circuits A 2.50-and a 7.30-uF capacitor can be connected in series or parallel, as can a 29.0-and a 100-kΩ resistor. Calculate the four RC time constants possible from connecting the resulting capacitance and resistance in series. Both the resistors and the capacitors connected in series 0.240 s You are correct. Your receipt no. is 155-8312 The resistors connected in series and the capacitors connected in parallel 1.26 s You are correct.

Answer 1

Time constant = Capacitance $\times$ resistance

for the first 2 part, the answer is correct so I will you help with other 2( which you can not get right)

3) when resister in parallel their equivalent

R_eq = ( Reciprocal rule)

(29 × 100)/29 22.48|Kohm 100

capacitor equivalent

C_eq=2.5+7.3=9.8 micro F

Time constant=

(22.481 × 103ohm) × (9.8 × 10-6F) 0.22s

4) when capacitor in series

ce q-(7.3 × 2.5)/(2.5 + 7.3)-1 . 8622tnícror

Time constant =

(22.48 × 10°ohn) × (1.8622 × 10-6F) 0.04 19s
