Identifying parallel circuits

salesm21
salesm21 over 8 years ago

To anyone out there,

I have a circuit for my class and am stumped on the identification of it. I cant figure out weather or not the bottom branches are in parallel or in series. Any thoughts? Any tips or tricks? I know what parallel means but I don't understand the wire that's in-between the resistors and the capacitors. Since the capacitor branch does not end at the same spot as the other capacitor does this mean its not in parallel?

    R2 and R3 are in parallel and are equivalent to 720ohm, and C2 is in parallel with C3 and are equivalent to 2.2nF. This results in a circuit composed of R1 and C1 in series with the 2.2nF capacitor and…

    Opps, i see that i managed to submit a typo: the equivalent capacitance for the two parallel capacitors is 3.2nF, not 2.2 as i managed to write just now.

    First off, you should always use a bit of logic to validate your answers. The equivalent resistance of two resistors in parallel will always be smaller than the smallest of the two resistors, and the equivalent…

    R2 and R3 are in parallel and are equivalent to 720ohm, and C2 is in parallel with C3 and are equivalent to 2.2nF. This results in a circuit composed of R1 and C1 in series with the 2.2nF capacitor and the 720 ohm resistor, which can also be reduced to one resistor and one capacitor - i leave it up to you to calculate the equivalent resistance and capacitor of the final circuit.
