5-mu or micro f capacitor is charged to 110 v and is then connected across a 600-ohm resistor. what is the initial charge on the capacitor? c * [2.5 points] 1 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] what is the initial current just after the capacitor is connected to the resistor? 0.18 a * [2.5 points] 1 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] 0.18 ok what is the time constant of this circuit? 0.003 s * [2.5 points] 2 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] 0.003 ok how much charge is on the capacitor after 6 ms?

a) Qo=550 *10^-6 C; b) Io=0.18 A; c) τ=3 ms

Explanation: In order to explain this problem we have to consirer the capacitor expresion given by :

C=Q/V then Q=C*V

the initial charge of the capacitor is:

Qo= 5*10^-6*110=550 μC

When the capacitor is connected to a resistor the stored charge is consume at the resitance as a current (dQ/dt):

The charge as a function of time is given by;

Q(t)= Qo*e(-t/τ) where τ is the equal R*C and represent the time constant.

the we have that the current is:

I=dQ/dt= (Qo/τ)*e(-t/τ)=(Qo)/(R*C)*e(-t/R*C)

Io=(Qo/τ)=(550*10^-6)/(600*5*10^-6)=0.18 A

overcharge is the right answer system

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
