Determine the equivalent capacitance of each of the circuits in the figure shown.
Note: I leave the image of the exercises in Spanish, but it is easy to understand.
Also in the other image is the correct final answer, for checking.
IMPORTANT:Please, preferably the procedure should be digital, not on paper.This way I understand better.I would appreciate it very much!
Refer to the diagram below. Compute the total capacitance, voltage and charge across each capacitor given that the total voltage is 120V. Please help, I've been getting ridiculously long decimal values and I don't know what to do.
A. Find the equivalent capacitance of the combination shown in the figure. (C2 = 2µF, C3 = 3µF)
B. Determine the charge on each capacitor, if there is a potential difference of 900V
C. Determine the voltages across each capacitor

You are told that the spacecraft uses a "start capacitor" that must reach a required voltage in order to start its engine. This voltage is determined by the fixed capacitance and charge as a function of time, q(t) . These capacitors are charged and stored in your current location and must be brought to the spacecraft. Your computer provides you with the following definitions: Charge: The charge as a function of time is q(t)=∫i(t)dt , where i(t)=36t^5+15t^2−6 is the current as a function of time. You need to provide the computer with the function q(t) in order for it to appropriately charge the start capacitor. If an unknown constant is needed, it can be included using "+ C", being sure to use a capital letter as the lowercase is used for capacitance. q(t)=arrow_forward
