Circuits
Overachieving and under-appreciated, circuits are the foundation that our technological society is built on. Now's your chance to find out not only how they work, but why. Questions regarding the physics behind voltage, resistance, capacitance, inductance, transistors, LEDs, switches, and power supplies; and how they're used to create analog and digital circuits, should be directed here.

By altering the time constant (CxR) in such a way that there is little distortion. To ensure minimum distortion, CR should be much greater than 5 to 10 times that of T. C is capacitance in farads, R in ohms and T in seconds. For detailed knowhow on this matter, you may consult low pass/ high pass/ band pass filter designing.
Why maximum power is transferred when impedance of source and load is same?
Note that this is about maximum power transfer, NOT about maximum efficiency.The source resistance is assumed to be constant; the load resistant variable.
If you know about calculus, you can derive the maximum power transferred by writing an expression for the power as a function of the variable load. You need no advanced calculus for this - just derivatives, which are used to get the maximum or minimum of a function (as well as high school algebra, of course). You can find the derivation (for the simplified case of a purely resistive circuit) in the Wikipedia article on "Maximum power transfer theorem", as well as a link to the more general case.
Why the net resistance increases in series connection?
series network consists of components i.e resisters connected end to end. since their is only one path for the flow of current. but potential drop across each resister is different. so thats the reason that series network has maximum resistence then the highest resister in combination. the same amount of current passes through each resister.
How do you calculate total emf in series connecte cells?
With cells connected in series, the total emf of the 'stack' is simply the sum of
the individual emf's of the individual cells.
-- Even if one cell is connected backwards in the string. Then its emf is considered
negative when the sum is being performed.
-- All of this is true only as long as there is no external connection between the
ends of the stack, you're measuring the emf on an 'open-circuit' basis with a
voltmeter, and the cells are not providing any current to an external circuit.
Once the series combination of cells is connected to an external circuit and begins
to produce current, the total emf at the terminals of the stack will decrease. It'll
depend on the magnitude of the current, and on the 'internal impedance' of each
cell. If the cells are not precisely identical and in identical states of charge, then
a calculation of the total emf is virtually impossible.

What can be used to produce a continuous flow of charge?
A battery will do this, when connected to a closed circuit (for a while).
Characteristics of good acceptor circuit?
It needs to be in good working order. If there are any cracks or tears in it, then it might not work properly.
It is a device with multible resistors that controls the speed of a blower motor.
It is a resistor or a group of resisters used to control the flow or current in a circuit. Like the resistor block in a car controls the speed of the a/c blower.
An insulator is a material that does not conduct electricity. More specifically, it is a material that is chosen to prevent electricity passing from one point to another. Typical examples are the plastic covering on cables, plastic cases around electronic circuits and the body of circuit boards which support copper tracks but keep them isolated from each other.
Advandage and disadvandage of berry transformer?
Berry transformer has good ventilation provision as compared to other types of transformer
Why there are only RC filters and not RLC filters used with IC.why inductor is not used?
The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.
How does a pull up resistor works?
A pull-up resistor is used to "pull-up" a signal to prevent it from floating or creating an undefined state. Typically a digital input might be looking for a ground or low state to indicate a state. The pull-up resistor is attached to the signal line and to a level which will "pull" the line to a high level in the absense of a low signal. The effect is to provide a reliable hi or lo to an input. The pull up may located close to an input or directly at an output to effect the results. Some eletronic devices have the pull-up devices internally installed.
Where is the start run relay located on a 1989 dodge 250 van?
It's located on the driver's side fender near the strut tower.

There can be no answer for this without knowing how strong a resistor is involved. (Ohms)
Why is a complete path required for the current to flow?
If there is no complete path, excess electrons will very quickly build up at some place, and repel further electrons - no more current will thus flow.
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
