No. Current and voltage are directly proportional to one-another and both are related to resistance by Ohm's law:

V = IR

or

Volts = Current * Resistance

So the current will depend upon the voltage and the circuit resistance by rearranging the above equations:

I = V/R

Meaning that the current will decrease as circuit resistance is increased if the voltage remains constant.

An active device amplifies the signal by some value - such as an active filter using an OPAMP.

A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.

Transistors and/or relays.

charge-coupled device

There are many reasons to use a simple diagram to map complex electrical circuits. By using basic wiring diagrams, the larger picture becomes easier to understand. If you are trouble shooting a specific problem with your motor (i.e. battery is completely drained) and you want to find out whether their is a short or grounding issue, you can follow the simple diagram to diagnose the problem. Starting from the battery, follow the diagram to the next piece of hardware and test/fix the issue as you go. Then, continue to the next piece. Continue this process until you come back to the battery. This eliminates some of the head aches, and can also save money in the long run.

No. A resistor doesn't slow down the speed of the current, it limits how much can flow. Current can only flow if there is a complete circuit. The curent flows from the negative terminal of the power supply, through the load (resistors, lamps, or whatever), back through the positive terminal. The same number of electrons that leave the negative terminal must return through the positive terminal, so the current must be the same anywhere in a series circuit. More resistance just limits the current more. Think of a single file line of people, standing so close to each other they are touching, trying to squeeze through a series of narrow openings. Each opening slows the line down a bit, but the same number of people that enter the line also come out at the other end. Since a person can't move until the one in front of him does, the number of people passing any particular point every second is the same no matter where you check. The more restrictions (resistance), the fewer people per second. Make sense?

To combine the signals of multiple microphones, you add (sum) their electrical voltages, just like the sound waves from multiple singers sum in the air.

To measure the voltage produced by the microphone without affecting it, you need amplifier circuits with high input impedances. These amplifiers must also have a widely variable gain (trim control), since there are many different microphones with different output levels, and you want them all internally at the same level. Then you might have EQ or other controls to manipulate the sound of each microphone.

Then there is an overall volume control for each microphone, for setting the relative level of each. Then the weighted signals go into a summing amplifier to be added together, and then to an output.

No, the output of monostable multivibrator does not oscillate. As it has only one stable output we do not get oscillations. We get a square wave as output.

Device which has aleast one transistor with channel length 0.35 um is called 0.35 micron technology.

This question really needs a little more context, but an attempt would be:

1: Properties common to both NAND and NOR gates:

- they are both electronic logic circuits (as implied by the term "Gate")

- they both compute a primitive single valued Boolean function of two or more input terms

- they both implement the inverted output version of their primitive (the leading 'N')

- there are no families of logic components that implement one and not the other in their catalog

2: differences:

- the NAND output is TRUE iff any of its inputs are FALSE

- the NOR output is FALSE iff any of its inputs are TRUE

- the NAND circuit is much simpler to implement than NOR

(NB: the term 'iff' means 'if and only if' - it is not a typo)

The 7475 is a TTL MSI circuit that contains four D latches, it is also known as 'quad bistable latch.' The 7475 is mostly used for temporary storing 4-bit nibbles of data. Any length of data can be stored by using more than one 7475 chip. When all four clock input pins connected to logic high clock pulse, input data is loaded into the D latches(each latch is D Flip-Flop) and appears at the Q output and remains there. After clock pulse goes logic low, the output at Q and Q' still holds input data till clock pulse changes it logic state back to 'High' and input data is changed.

Alarms which are generated due to the failure of any link or card on the Sdh equipments are sdh alarms.

ic made from bjt is known as bipolar ic

thermocouple,piezoelectric transducer,photoelectric transducer.

No.

As base current decreases, so does collector current.

It depends on the type of Power systems Whether AC ( single or multi phases) or DC ( 2 or 3 wire ) .....ETc

number of conductors

magnitude of the magnetic flux

true

Depending on the package type and where you buy it, one 4017 costs somewhere between $0.30 and $1.00 US.

we can use monostable multivibrator.But generally its o/p is a square wave so to get a pulse type waveform,we may use differentiator after monostable multivibrator....

When applied to electrical waveforms, a 'harmonic' is a multiple of the fundamental frequency.
