I'm not sure what you mean about "without any data". Can you just solve the question using series & parallel combinations of resistors? Since they are all equal to "R" in value, that makes it pretty easy...nicholasrivera said:
But I am not sure what I am supposed to get as an answer will it just be in terms of R?berkeman said:
When I go to that link, I don't get anything related to electronics. Mostly just ads.nicholasrivera said:
Yes. If there were just 2 resistors in series, the answer would be "2R". If there were just 2 resistors in parallel, the answer would be "R/2". Right?nicholasrivera said:
I get a small schematic mixed in with the ads for a few seconds, and then a sea of ads washing out the schematic... Annoying....Scott said:
sorry used a terrible image hosting site I fixed the link https://imgur.com/a/LWcIC.Scott said:
Thanks. Now can you show us your work step-by-step to do the series & parallel combinations we are suggesting?nicholasrivera said:
https://i.imgur.com/ubVARZs.jpg there's my answer I got 6R but I am not sure if I combined the resistors correctly.berkeman said:Thanks. Now can you show us your work step-by-step to do the series & parallel combinations we are suggesting?
That can't be right, since if the middle parallel resistor were not there, the other resistors would add up to 5R.nicholasrivera said:
No, that doesn't look right, and I honestly am not following what you are doing.nicholasrivera said:
To calculate the equivalent resistance of a circuit without data, you will need to use Ohm's Law and Kirchhoff's Laws. Ohm's Law states that resistance (R) is equal to voltage (V) divided by current (I). Kirchhoff's Laws state that the sum of all currents entering a node is equal to the sum of all currents leaving a node, and the sum of all voltages around a closed loop is equal to zero. By applying these laws to the circuit, you can solve for the unknown resistance.
Finding the equivalent resistance of a circuit is important because it allows us to simplify a complex circuit into a single, equivalent resistor. This makes it easier to understand and analyze the behavior of the circuit, and can also help in selecting the appropriate components for the circuit.
The equivalent resistance of a circuit can be either higher or lower than the individual resistances, depending on the configuration of the circuit. In series circuits, the equivalent resistance is always higher than the individual resistances, while in parallel circuits, the equivalent resistance is always lower than the individual resistances.
Yes, there are some shortcuts and formulas that can be used to find the equivalent resistance in certain types of circuits. For example, in a series circuit, the equivalent resistance is equal to the sum of all the individual resistances. In a parallel circuit, the inverse of the equivalent resistance is equal to the sum of the inverse of each individual resistance. However, these shortcuts may not be applicable in more complex circuits.
The units of equivalent resistance are the same as those for individual resistance, which is ohms (Ω). This is because the equivalent resistance is simply a representation of the total resistance in the circuit.
