Question

5. Given a resistance of 147 and a capacitance of 355 F,
what is t1/2?
t1/2 =  [milliseconds]
(Answer to one tenth of a millisecond or N/A if there is no answer.)

6. Given a resistance of 147 and a capacitance of 355 F,
what is the time constant (tau)?
(tau) =  [units reserved for next question.]Use normal unit for this answer not milli nor micro units.

7. You have an RC circuit and you measure the "zero" voltage to actually be 2.685 [Volts].

The peak voltage is measured to be 8.922 [Volts].

At what voltage value will you look for t4 = time stamp for 15/16 total charge?
[Volts]
(Use three significant figures or N/A if there is no answer.)

Explanation / Answer

Ans 5.  your question is not clear...
if you want TIME CONSTANT..
RC = 147 x 355 x 10^-6 = 0.0522 sec or 52.19 msec
or after what time its voltage became a half of charged one..
V = Vo ( 1 - e ^ -t/rc )
V / Vo = 1/2 >>> e ^-t/rc = 1/2
t / rc = 0.693
t = 0.0522x0.693 = 36.17 msec

Ans 6.

RC, (tau) = 147 x 355 x 10^-6 = 0.0522 sec or 52.19 msec
