Question

The Equivalent resistance between points A and B is 99.83 ohms. What is the value of R? I can't upload a pic for some reason, but imagine a horizontal line extended from point a , there is a resistor of 63 ohms.. it then continues to a junction where it splits both 90 degrees up and down. it makes a box and then continues on to point b in the same manner that it began(horizontal line).. basically a box that is divided by a line, with the line vanishing inside the box. There is a second resitor on the top of the box which is 65 ohms and third resistance on the bottom of the box which = R. Can you help me find out how to get R.? I keep trying to combine R1 and R2 in series or R2 and R3 in parallel, but I cant get it.

Explanation / Answer

Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur very frequently. Components connected in series are connected along a single path, so the same current flows through all of the components.[1][2] Components connected in parallel are connected so the same voltage is applied to each component.[3] A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit. In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.[1] In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.[3] As an example, consider a very simple circuit consisting of four light bulbs and one 6 V battery. If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel. If the four light bulbs are connected in series, there is same current through all of them, and the voltage drop is 1.5 V across each bulb, which may not be sufficient to make them glow. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is 6.0 V across each bulb and they all glow. In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function
