But I am confused which wire to use?gneill said:
Wire is wire... Remember, when you collapse a series of components down to one then you will be eliminating any nodes that were along the path, leaving just the two nodes at the ends where the "new" component attach. So don't expect your previous coloring scheme to survive a series reduction. Replace the wiring for the "new" capacitor with the color of the end nodes.gracy said:
Yes, that's good!gracy said:
This is the original figure . (No, I'm not clairvoyant.)SteamKing said:
Yellow or blue?what if I had used yellow color instead of blue.It would be also correct,Right?It will also give 2C as equivalent capacitance.gracy said:
The colors you use do not matter; they're merely an aid for identifying individual nodes when a circuit layout is complicated (or if it's purposely made tricky to interpret for a school exercise!). The colors don't change the circuit.gracy said:
Practice. Recognizing parallel or series connections in a circuit gets easier with practice.gracy said:
If someone were to present it to you and ask if it was a valid circuit, the short answer would be no. A longer answer would require some context.gracy said:
Anyone ?gneill said:
What is not clear?gracy said:
That 'one' will be the equivalent capacitance.gracy said:
You should first 'calculate' the equivalent capacitance. Here it's C/3. Then replace all the capacitors in the original diagram with a wire. Then break the wire (anywhere between A and B) and insert the equivalent capacitor.gracy said:As in here
how you decided that equivalent capacitor would be in place of middle (component )capacitor?
That's what I asked!cnh1995 said:
Since there is wire elsewhere, it doesn't matter where you place the equivalent capacitor as long as it's between A and B.gracy said:
Equivalent capacitance is a concept in electrical engineering that refers to the combined capacitance of multiple capacitors connected in a circuit. It is a measure of the overall ability of the circuit to store electrical charge.
Equivalent capacitance is calculated using the formula Ceq = C1 + C2 + C3 + ..., where C1, C2, C3, etc. are the individual capacitances of the capacitors in the circuit. This formula applies for capacitors connected in parallel. For capacitors connected in series, the formula is 1/Ceq = 1/C1 + 1/C2 + 1/C3 + ...
Equivalent capacitance is important because it allows us to simplify complex circuits and calculate their overall capacitance. It also helps in designing and troubleshooting electrical circuits.
In series equivalent capacitance, the individual capacitances are added reciprocally, while in parallel equivalent capacitance, they are added directly. This means that in series, the equivalent capacitance is always less than the individual capacitances, while in parallel, the equivalent capacitance is always greater than the individual capacitances.
Capacitors in a circuit affect the equivalent capacitance by either adding to or decreasing it, depending on whether they are connected in series or parallel. Series capacitors decrease the equivalent capacitance, while parallel capacitors increase it. Additionally, the size and type of the capacitors also impact the equivalent capacitance.
