in the circuit shown in the figure, the S switch is closed at t=0 and the capasitors, which are completely empty, begin to fill. Here E=30V, C=3 uF and R=40 ohm.
A) what is the time constant of the circuit, T, in the units of microseconds?
B)when t=T, what is the total charge, in units of microcoulomb?
Given the current through a point to be i(t) = 5.66 cos( 2.3 t), in amperes, determine the total amount of charge, in coulombs, flowing through the said point during the time interval 2.34 s < t < 6.09 s.
When the switch S is toggled to the left, the capacitor C charges through the resistor R. When the switch is toggled to the right, the capacitor discharges current through the patient's torso, modeled as the resistor Rtorso, allowing the heart's normal rhythm to be reestablished.
(a)
If the capacitor is initially uncharged with C = 7.00 µF and = 1270 V, find the value of R (in ohms) required to charge the capacitor to a voltage of 795 V in 1.70 s.
Ω
(b)
If the capacitor is then discharged across the patient's torso with Rtorso = 1270 Ω, calculate the voltage (in V) across the capacitor after 4.50 ms.
