Consider the above infinite chain of resistors.

Infinite resistor ladder solution. Bond vol2 no3 resistance of an innite ladder we want to compute the input resistance to a resistor ladder network of the form in figure 1. With long or infinite ladder configurations ill try to see if there is a symmetry that lets me fold up the parallel series combinations below. This network can be thought of as an innite train of l sections each with a horizontal.

The solution notice that the entire resistor network is made up of one simple repeating unit ie as the question states this unit repeats itself infinite number of times. Ive split the resistor and ive done r2 rr r20 solving for r and i dont get the right answer. An infinite ladder is constructed with 1w and 2w resistors as shown in the figure below.

Maybe try the code keyword in square brackets to force non proportional spacing or just attach a pdf or other document. Firstly lets only consider part of the problem to the right of the a b junction as the left and right side are identical and in parallel so the total value would be the value of one side divided by 2. Its hard to visualize the resistor ladder that you are asking about.

Find the effective resistance between points a b. Nu meditation music recommended for you. Healing deep sleep meditation sacral chakra meditation balancing duration.

Sleep chakra meditation music. Calculate the effective resistance r in ohm of the network between the terminals a and b given that each of the resistances labelled r4180 ohm. The solution is the equality rlrrfrac1frac1rfrac1rl which is true as if we remove three leftmost resistors we end up with exactly same ladder.

We get good result because the total resistance is finite as may be proved by representing the total resistance as a recursive sequence and proving its convergence. The problem were trying to solve for here i.
