Circuits

If by "its own wire" you mean they are connected in parallel, then one bulb won't affect the others.

With an unknown voltage you should start out with the highest voltage setting on the meter. Doing this reduces the risk of "pegging" out the needle on an analog gauge or overloading the input of a DMM. Most DMM's are auto-ranging though.

The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor.

As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.

In America, a 2-pole breaker is controlling 240V. 120V per leg.

Low Power Consumption, Small size and has light weight.

-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes.

-- The current is always the same at every point in a series circuit, no matter how many

resistors of the same or different values are in the circuit.

By using Ohm's law, you are able to find the resistance of a circuit, knowing only the voltage and the current in the circuit.

In any equation, if all the variables (parameters) are known except one, that unknown can be found. For example, using Ohm's law, if current (I) and voltage (E) are known, resistance (R) the only parameter not known, can be determined:

Basic formula:

Remove the divisor by multiplying both sides by R:

Result of step 2: R x I = E

To get R alone (on one side of the equation) divide both sides by I:

The basic formula, transposed for R, is:

the appliance will burn out, eg if it is a 60 watt light bulb it will burn at 120 watt for as long as the fillament can take it and that wont be long

To start, while integrated circuits are smaller and usually require less power to operate, they are extremely difficult (if not impossible) to modify or repair. They almost always have to be replaced, and if the IC or "chip" is a proprietary chip, then the entire unit may have to be replaced. The IC is also more susceptable to electric damage from a power surge than its beefier component cousins. IC's have the advantage in weight, size and power consumption, giving IC's the nod on portability. They are also less prone to damage from physical jarring -- known as "solid state." When would you use non-IC components? High voltage applications certainly! Also, most musicians prefer the sound quality of tube amplifiers over transistor amps. Prior to the widespread adoption of integrated circuits, electronic systems consisted of components, such as transistors, resistors, capacitors and resistors, wired together on a board. This was labour-intensive and therfore expensive, as well as contributing to electronic faults when the process worker installed the wrong component, or allowed components to touch. Integrated circuits eliminated all that, because they can be consistently mass produced to very high quality standards. One disadvantage of integrated circuits is that they can be unsuitable for custom designed equipment, because high volumes are needed in order to justify the design and tooling costs. One way of creating some flexibility is to use a hybrid design - with key components in the IC, with some components left outside the IC to provide flexibility in component values. Another disadvantage of integrated circuits is that design corrections and incremental design improvements are not readily made. If a design error is found in a traditional circuit, it is relatively easy to modify each system to fix the problem, even under warranty. A potential disadvantage of integrated circuits is the cost of replacing an IC that has failed. However, this is a more apparent than real problem, because labour is usually the main cost of repairs. While the cost of buying a new component may be higher, the labour cost of diagnosing and replacing it is usually lower.

An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.

By having the Supplemental Restraint System, (SRS) repaired. There is a problem with the air bags. Do not attempt to repair yourself.

On my 92 B250, the voltage regulator is integrated right into the alternator.

The engine computer is the voltage regulator on a 1989 Dodge Ram Van.

It doesn't matter, unless we're talking about some bulbs with integrated switching power supplies, in which case it might make sense to offset (distance) them by about (SwitchingFrequency / NumberOfBulbs) Hz, to make the general load appear mostly resistive. But in about 99.9% of the cases, the placement of a load (and a light bulb is a load) does not change the amount of current it uses as it's a property of the light bulb itself.

Of course, with LED lights it's possible to "go creative" with the placements of the LEDs and their resistors in such a way as to minimize current draw and power dissipation through heat, but I fear the gains would very well be rather negligible. Also, in-depth knowledge of said resistors and LEDs would be needed if someone were to undertake such an endeavour.

The standard unit of electric energy is the Watt Hour.

AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.

Stripping the wire in a homemade electromagnet would not make it stronger. The number of coils and the current passing through the wire are the main factors that determine the strength of the magnetic field produced by the electromagnet. Stripping the wire would affect the conductivity and integrity of the coil, potentially reducing its effectiveness.

The best way is still to follow the advice that was given to Richard Feynman for selecting gears in the mechanical analog computers he designed for the US military at the beginning of WW2 before joining the Manhattan Project: "...select from the middle of the manufacturer's catalog, because the ones at the beginning and end are hard for them to make reliably, if they were not then they would not be at the beginning or end of the catalog...". This applies just as well to electronic components now as it did to gears back then.

The generic op-amp would suffice for lab experiments. A number of summer amplifiers attached to a central amplifier attached to a comparator is what those at Robert Gordon University apparently use. The virtue of that design is that all those parts can be made from op-amps.

Although I have not tried it, a schmitt trigger, which can also be made from op-amps, can probably be used instead of a simple comparator - making analogue ternary (three-state) logic, in other words.

Cheers.

Not sure about the comparator. XOR is what I came up with, so we have two XORs.

This is the "exclusive OR" logic function. Build one out of standard resistors and transistors, or buy an IC with the XOR function already implemented, or use four two-input NAND gates. At least that's the way we did it in the 1960s. In analog circuits, a comparator.

When all parts of a circuit are composed of conducting materials, the circuit is said to be closed.

One condition could be a closed circuit, however it could be open if the components are not assembled or are assembled incorrectly.

Build a jumper wire with small alligator clips at each end.

Find the "B" terminal on the regulator and attach one of the alligator clips, find the "D" terminal and touch the terminal with the other alligator clip. You can touch the terminals a few times and it will produce a soft light spark. Under no circumstances touch the "F" terminal or any other part of the regulator or you could damage the regulator. Start the car and make sure the generator charges properly by the gauge indication.

I was trying to find this out too and learned that the game we called Michigan Rummy with different goals for each hand is really called Contract Rummy. If you search on that name you may find more information like I did. I don't know about eleven hands, but I remember the following sequences with sets consisting of 3 cards of the same rank/value (all 3's, all Jacks, etc); runs consisting of 4 cards of the same suit in consecutive order; aces count as 1's. 1. Two Sets 2. One Set, One Run 3. Two Runs 4. Three Sets 5. Two Sets, One Run 6. One Set, Two Runs 7. Three Runs. We usually only went to #6 and called that hand "Mr. Perfect", meaning you needed to have no discard when you laid down that last hand. Hope this helps.
