Question

A 18.5-µF capacitor is charged to 90.0 V, then discharged through a 75.0 ? resistor. After discharge begins, what amount of time $t_1$ will pass before the capacitor has lost 90.0% of its initial charge? $t_1 = $ 2.99 x10$^{-3}$ s Incorrect After discharge begins, what amount of time $t_2$ will pass before the capacitor has lost 90.0% of its initial energy? $t_2 = $ 1.49 x10$^{-3}$ s Incorrect What is the magnitude of the current $i_1$ through the resistor when the capacitor has lost 90.0% of its initial charge? $i_1 = $ 0.12 A What is the magnitude of the current $i_2$ through the resistor when the capacitor has lost 90.0% of its initial energy? $i_2 = $ 0.3792 A

          A 18.5-µF capacitor is charged to 90.0 V, then discharged through a 75.0 ? resistor.
After discharge begins, what amount of time $t_1$ will pass
before the capacitor has lost 90.0% of its initial charge?
$t_1 = $ 2.99 x10$^{-3}$ s
Incorrect
After discharge begins, what amount of time $t_2$ will pass
before the capacitor has lost 90.0% of its initial energy?
$t_2 = $ 1.49 x10$^{-3}$ s
Incorrect
What is the magnitude of the current $i_1$ through the resistor
when the capacitor has lost 90.0% of its initial charge?
$i_1 = $ 0.12 A
What is the magnitude of the current $i_2$ through the resistor
when the capacitor has lost 90.0% of its initial energy?
$i_2 = $ 0.3792 A

A 18.5-µF capacitor is charged to 90.0 V, then discharged through a 75.0 ? resistor.
After discharge begins, what amount of time t1 will pass
before the capacitor has lost 90.0% of its initial charge?
t1 = 2.99 x10^-3 s
Incorrect
After discharge begins, what amount of time t2 will pass
before the capacitor has lost 90.0% of its initial energy?
t2 = 1.49 x10^-3 s
Incorrect
