Circuits

The 4 main components of a circuit are:

(1) Switch - turns electric current on and off, closes and opens a circuit.

(2) Load - resists the flow of current and converts electrical energy into another form of energy (ex. light bulb)

(3) Wires - thin strips of insulated copper conducts the electric current, allowing it to pass through like a pathway, makes up the circuit.

(4) Source - gives the circuit the required electrical energy

A resistor can also be included as one of the components

150 mA is.

A transformer is not 'necessary'. The human race evolved, and developed

cultures, societies, disease resistance, and technology, without ever

seeing a transformer.

But there are specific situations in which desirable things can be accomplished

much more effectively and efficiently with a transformer than with any other

device or method. Here are a couple of examples:

-- If the voltage you have available is not the voltage you need, then you can

use a transformer to make the change. (But that only works for AC.)

-- You can use a transformer to change the output impedance of an amplifier

to the impedance of the speaker or earbuds you want to use with it.

It most likely stands for the Mutual Inductance seen between two inductors.

(15 volts) x (10 Amps) = 150 watts

If the capacitor isn't punctured or failed, then it becomes charged to the voltage

of the battery almost immediately after it's connected to it, and stays that way.

Yes. Electrolytic capacitors are polarized.

Capacitors with positive and negative poles generally have positive and negative marks. Generally, for capacitors with pins, the long end of the pin is the positive electrode. For cylindrical electrolytic capacitors, there will be a vertical line printed on the negative side of the capacitor. SMD capacitors generally have no positive and negative poles.

In a DC circuit . . . resistance.

In an AC circuit . . . impedance.

it is a transformer tht when u crank the crank, it walks

Reverberating.

bulb , bulb holder , wires and bataries are main compoments of a circuir

modulator

bulb, Motor, buzzer, battery

I need the diagram of diodes whith type GSa-L3-2

by sending electricity through them

There are no particular advantages or disadvantages of series or parallel circuits. Some circuits require one while other circuits require the other. Frequency filters often require one or the other depending on whether you need a pass or rejection filter.

Terminal

The 4017 is a 5-stage divide-by-10 "Johnson counter" with 10 decoded outputs

and a carry out bit. The 4000 series are CMOS devices.

In TTL, the 74142 is also designed as a decade counter, which makes it functionally

equivalent to the primary mission of the 4017. But it can't be called "equivalent" in

any other respect, because of the usual wide array of differences in power requirements

and input and output impedances between CMOS and TTL technology.

Interlocking systems are used mainly where definite operating and sequential procedures are to be followed. Applications are generally where the safety of a person working on equipment is in danger by someone inadvertently turning on the equipment and thereby inflicting injury.

Another application for interlocking systems is for access control. A simple, robust system, requiring no power, can be installed disallowing access by unauthorised persons into various areas of buildings, factories, plants etcetera. The limitations of interlocks are boundless and applications for safety or other reasons exist in all areas of industry.

forward bias

bandwidth decreases

think of a circuit with a cell , wires and a bulb. now think about a boiler and pump, pipes and a radiator. the cell is like the boiler and pump because it has the energy. the pipes are like the wires because they transfer the energy. the bulb is like the radiator because they use the energy changing it into light energy and heat energy when referring to them especially.

Advantages - very cheap, and easy to replace. Since they fail open circuit, a small low value resistor can be used instead of a more expensive fuse.

Disadvantage = waste power, by turning it to heat. If you follow the link below and study the circuit diagram you will see that current is flowing in both Rb1 and Rb2 even when there is no signal being amplified. That "quiescent current" is wasted because it is not achieving anything and power is consumed through the production of heat.

It converts light into an electrical signal. Opposite of what an LED does.
