A capacitor has capacitance 4 microC/Volt. It is placed in series with a resistance of 48 Ohms and 25 volt source. When the current in the circuit has built a charge of 67 microC on the capacitor, how much current will be flowing through the circuit?© BrainMass Inc. brainmass.com November 30, 2021, 12:32 am ad1c9bdddf
Please find the solution attached in two formats - XP Word format, and Adobe Pdf format.
The instantaneous charge on the capacitor as a function of time is:
And the current in the circuit is:
From the first ...
Solution also shows the derivation of the expression to compute the instantaneous charge on the capacitor as a function of time.
