Dc circuit Definition and 105 Threads

A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission).

    Can Hydrogen have a DC Circuit?

    [SOLVED] Can Hydrogen have a DC Circuit? I'm thinking of the hydrogen atom like it might be a DC type of electrical circuit, just for fun, but I am not sure what values to use for a couple of simple equations. Can somebody help me out? The equation is V=I*R I found an impedance value, Z...

    DC Circuit: Single vs. Two Bulbs Connected

    First one light bulb is connected to a battery. Then two are connected in series to the same battery. Here's the picture: http://home.comcast.net/~chou55/bulb.gif A) When two are connected, the battery puts out a) less current b) more current c) less voltage d) the same current B)...

    What Are the Key Factors Influencing Current and Resistance in DC Circuits?

    i just finished reading the circuit chapter in my book hoping it would answer a few of the questions i had in mind, it helped, but not as much as i had hoped...here are a few questions how quickly is a current established throughout a circuit when the switch is closed? (now i suppose the...

    Calculating Current in Parallel DC Circuit - Solving for I3

    I'm having trouble solving this problem: Three resistors(parallel) across a DC voltage source...If the total current through the circuit is I = 2.0A, what is the currect through the 12ohm resistor? The circuit runs into a junction which splits 3 ways. Along each path there's are resistors...

    Solving DC Circuit Problems: Determining Current in 8[Ω] and 4[Ω] Resistors

    a) I must determine the current in 8 [ome] resistor? Current in the 4[ome] ? a) I started out using ohms law. E=IR, ok. I took the difference between the Voltages eg.12-9 = 3V then multiply by 11 ohms total resistance. b) Did pretty much the same way except that 4 ohms is where most...
