Answer:
t = 0.04159 s
Explanation:
when a capacitor and resister are connected in series. charge on its plates decreases exponentially
[tex]q = qo * e^{\frac{-t}{RC}}[/tex]
where,
CHARGE q =15.0 C
INITIAL CHARGE q_0 = 30.0 uc
Resistor R = 20.0 F
capacitor C = 3.00
[tex]15 = 30* e^{\frac{- t}{(20* 10^{-6} * 3* 1000)}[/tex]
t = 0.04159 s
