# What is Resistive circuit: Definition and 13 Discussions

An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Linear electrical networks, a special type consisting only of sources (voltage or current), linear lumped elements (resistors, capacitors, inductors), and linear distributed elements (transmission lines), have the property that signals are linearly superimposable. They are thus more easily analyzed, using powerful frequency domain methods such as Laplace transforms, to determine DC response, AC response, and transient response.
A resistive circuit is a circuit containing only resistors and ideal current and voltage sources. Analysis of resistive circuits is less complicated than analysis of circuits containing capacitors and inductors. If the sources are constant (DC) sources, the result is a DC circuit. The effective resistance and current distribution properties of arbitrary resistor networks can be modeled in terms of their graph measures and geometrical properties.A network that contains active electronic components is known as an electronic circuit. Such networks are generally nonlinear and require more complex design and analysis tools.

3. ### Conductive Silicon Carbide [Carborundum]

I am trying to create a conductive Silicon Carbide (SiC) heating element. The US patent 650234 "Process of making carborundum articles", filed in 1899 states essentially that crushed SiC crystals can be be glued together (using diluted glue) then sintered. It states that the addition of 15-20%...
4. ### No. of Electrons on Hard Disks: New vs Used

Is the no. of electrons on a brand new unused and untested harddisk is different from no. of electrons on a used hard disk completely filled with data. i mean will there be even a change of one electron? Please consider the following points before answering: 1- Does all the electrons from a...

Homework Statement Hi everyone! I'm trying to find the thevenin equivalent for part A of this circuit: http://imgur.com/4Jdg8w8 Homework EquationsThe Attempt at a Solution I first remove part B, that is, open circuit it entirely. Then I try to find Voc across the two terminals that are open. I...
6. ### Resistive circuit - ladder problem

Hey! 1. The problem Figure shows a very long ladder where every part has a resistanse of R. What is the resistance between A and B if the ladder can be approximated to be semi-infinite (the ladder has a beginning but no end).2.The figure 3. The attempt The first three resistances have a...
7. ### Engineering Series Resistive Circuit Problem Solution

Homework Statement http://puu.sh/6PZNJ.png Homework Equations This is supposed to be a pretty easy problem, but can i assume the resistors are in series? The other loops are throwing me off. The Attempt at a Solution
8. ### Engineering Resistive Circuit with Multiple Voltage Sources: Finding Power Absorbed

Homework Statement I need help solving this problem. I don't understand what to do when there's 2 voltage sources. The problem asks you to find the power absorbed at each resistor http://www.facebook.com/photo.php?fbid=2950199437043&set=a.2950198837028.2154160.1323079519&type=3&theater...
9. ### Battery draining in resistive circuit

When I was a kid listening to a transistor radio under my pillow late at night I used to wonder whether turning the volume down low would delay the gradual loss of battery voltage. My doubts centered in the fact that the volume control was (at least in those days) a variable resistor. I reasoned...

Hello all, I'm a new member. I've decided banging my forehead until its red will not make me any more able to solve my practice problems. I hope I haven't posted this in the wrong forum but here is the question in concern: Select R in the circuit so that VL= 5 V (see circuit in attachment...
11. ### Power Dissipation in Resistive Circuit Conceptual Question

Hey guys, so I have a homework question that I have already solved one way, but when I try it another way I can't seem to get the correct answer. First of all, the question is: "A single resistor is wired to a battery as shown in the diagram...

13. ### Why must voltage drop across a resistive circuit?

Hi, I am having difficulty understanding why potential must drop completely over a circuit from the high side of the source to the low side of the source. I've seen this statement in several books now with no further explanation other than "it must". Consider a simple dc circuit consisting of...
