yes it is. Of course waht do you think. yeh it is i think

you could use a step down transformer if you had no other option. but the best thing to do is run a 220 feed directly from the fuse panel Step down transformers get very hot and do not last forever

Yes you can - in principle, and in many cases. As long as the form factor of the new capacitor is the same as the form factor of the former capacitor, and as long as the maximum voltage of the new capacitor is higher than the max voltage of the former capacitor, you can often replace a lower-rated with a higher rated capacitor.

However...

Apart from the nominal capacity and maximum voltage rating, you should also consider the capacitor's design. There are many ways to make a capacitor, from tiny ceramics over various plastics and metal foil combinations to electrolytic capacitors. Apart from the capacity and voltage rating, the different types of capacitors also vary in a lot of other aspects: impedance, precision, drift with time and drift with temperature, are just some.

Electronics designers typically choose the capacitors carefully, and considering all those aspects. Only when those aspects don't matter much, designers tend to chose the cheapest technology. In such a case, you're safe to replace.

In most cases of capacitors rated at 1 micro Farad and above, electrolytic capacitors are used (typically small cylinders). Those are typically selected because they offer excellent value (capacitance) for money, and you're typically safe to replace them, subject to above rules.

CAUTION: some capacitors have a distinct polarity. You must make sure to observe the polatiry when replacing polarized capazitors. Failure to do so can result in serious harm (basically, the part might explode).

• only one dc supply is necessary.
• Operating point is almost independent of β variation.
• Operating point stabilized against shift in temperature.

When a clock signal is applied to a flip flop the output will change state from a binary 1 to a binary zero or visa vera on each clock pulse.

A latch when triggered by a clock signal will maintain its state until it receives a reset to unlatch it.

A:a latches not a flip flop but a switch set or reset waiting for a signal to close as a switch.

The electron was discovered by using cathode ray tubes. When it was discovered that the cathode ray diverted away from the negative end of a magnet to the positive end, it revealed that there was a negative particle present in the ray.

how to measure the length of elements and spacing of elements

In its simplest form, the starter of a dc motor is a variable resistance in series with the armature circuit of dc motor to reduce the high starting current so that the armature winding does not get overheated and burnt while the motor isgetting started. As the rotating armature of dc motor picks up speed, the starter resistance is gradually reduced so that the motor is able to attain its full speed when the starter is not expected to offer any additional resistance in series with the armature winding of the dc motor. At full speed the motor starts running normally, of course, without the help of starter. In other words, the starter offers resistance to armature current during starting of dc motor only. Under normal working condition of dc motor , the starter is electrically out of armature circuit of the motor. The starter protects the armature of dc motor from getting damaged. The electromotive force (emf) induced in the armature winding during starting builds up from zero value to max value to restrict the armature current within the permissible value at full speed. As the speed of armature/motor build up, armature induced emf also starts building thus reducing the role resistance offered by the starter, hence requiring it to gradually reduce as the motor picks up full speed.

This is a difficult question to answer because of all of the variables in so many different homes. The size of the home is one of the variables. The type of heating is another variable, whether it is electric or gas. How the hot water is heated in the home electric or gas. For example, I have a 3200 sq foot home and I use 1600 kWh every two months.

yes

A battery is condutor because it free to move

I suppose so. If a three input NAND is used as a two input device, the third input can be viewed as an inhibit input.

Also some NAND devices can be "3 stated" where the output goes to a high impedance.

The device that increases or decreases the voltage impressed across a power line is known as a voltage regulator.

A voltage regulator is a type of transformer where the primary and secondary turns ratio are fairly close; one (primary or secondary) often has a tap changing ability to add or remove several windings, allowing more dynamic control of voltage.

Semiconductors may be used to fabricate electronic devices. This is done quite often.

Most of the electronic devices they're used for are called "transistors". Often, several

transistors are combined in a single small device, called an "integrated circuit".

A few examples of where these devices may be found in real life include . . . -- almost every radio in the world

-- almost every TV set in the world

-- almost every landline telephone in the world

-- every TV remote

-- every GPS

-- every CD/DVD player

-- every cellphone and every smartphone in the world.

Fundamental frequency = 1st harmonic = 256 Hz

2nd harmonic = 1st overtone = 512 Hz

3rd harmonic = 2nd overtone = 768 Hz.

Look at the link: "Calculations of Harmonics from Fundamental

Frequency".

It means an 8 bit parallel I/O interface, as opposed to 8251 which is a serial I/O.

The battery has 6 volts across its terminals. The way to discover it is to apply Ohm's law. It (Ohm's law) comes in 3 "flavors" that look a bit different but all say exactly the same thing. Here they are: E = I x R [Voltage equals current times resistance.] I = E/R [Current equals voltage divided by resistance.] R = E/I [Resistance equals voltage divided by current.] In these equations, voltage is E, current is I and resistance is R. They are measured in units of volts, amperes (or amps) and ohms, respectively. In your problem, we have the resistance (R) and the current (I). We need to find the voltage (E), and the formula E = I x R is the logical choice to discover the voltage. As E = I x R here, E = 0.75 x 8 = 3/4 x 8 = 6 volts. Piece of cake.

Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule.

secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary.

eg;

240v \ 12v = 20 (factor)

this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.

RF is short for Right Fielder.

In the context of the category where this question was posted, RF probably refers to "radio frequency". "Radio frequency" usually refers to a rate of oscillation in the range of about 30 kHz (30,000 cycles per second) to 300 GHz (300,000,000,000 cycles per second). This is the range of frequencies of electromagnetic signals we call radio waves. Although RF usually refers to electrical rather than mechanical oscillations, mechanical oscillations in this range can also be referred to as "RF" (that use is a bit obscure though).

state diagram of d flip flop is same as applied input it means.

>if you are going to 0 to 0 than Qn =0

>if you are going to 0 to 1 than Qn= 1

>if you are going to 1 to 0 than Qn = 0

>if you are going to 1 to 1 than Qn= 1

we saw that output is equivalent to applied current input.

ANSWER: There are no diagrams but rather function MAPS where is every input/ output is taken care of its ambiguity to respond.

The following is the closest I can get using character map:
