There is insufficient information in the question to properly answer it. You need to also know the voltage or, alternatively, the power in order to find the resistance given the current. Please restate the question.

The total resistance in a series circuit is determined by adding (summing)

the individual resistances of each component in the circuit.

Comunication is important. the telephone(invented by Alexander Graham Bell) let people talk to each other easily. since comunication is VERY important it changed lives.

I was told it is

x(n) = 10*sin(2*pi*fo*Ts(n-1)) + 8*sin(2*pi*2*fo*Ts(n-1)) + 6*sin(2*pi*3*fo*Ts(n-1))

This should work if the form factor fits your application and other ratings are not exceeded. You want the same capacitance and make sure there are not any embedded components like a bleed-off resistor in the replacement that aren't in the original.

To drop a 12 volt source to 6 volts with a resistor, you have to drop 6 volts. The value of the resistor you need would be 6 divided by the current the device pulls in amps.

For example, if the device pulls a half an amp the resistor has to be 6/0.5 or 12 ohms. As this device runs on 6 volts and draws 1/2 amp, it's wattage is 3 watts (volts x Amps). Common practice is to double this, or the resistor will probably get too hot and may open. I'd use a 10 watt to resistor to maintain a good margin for safety, and they're readily available.

Use a 12 ohm, 10 watt resistor.

Wind turbines are a form of renewable energy that are powered by the wind. The amount of time it takes for a turbine to start up depends on the wind speed on the day, on a very windy day they can be up to full speed within 2 minutes.

Power is another term for watts. It is the product of amps flowing in the circuit, times the voltage in the circuit. The amount of power the circuit consumes is governed by the resistive or inductive load.

Heron of Alexandria invented a steam powered rotating ball in Circa 100 AD. This is the first recorded steam power.

Thomas Savery (1650-1715) was an English military engineer and inventor who in 1698, took out a general patent covering all possible means of pumping water by steam power. It was based on Denis Papin's Digester or pressure cooker of 1679.

Thomas Savery had been working on solving the problem of pumping water out of coal mines, his machine consisted of a closed vessel filled with water into which steam under pressure was introduced. This forced the water upwards and out of the mine shaft. Then a cold water sprinkler was used to condense the steam. This created a vacuum which sucked more water out of the mine shaft through a bottom valve.

Thomas Savery later worked with Thomas Newcomen who had actually invented the atmospheric steam engine and had to share his success with the patent holder.

The first steam engine was invented by Thomas Newcomen in 1712 to pump water from mine, the first being installed in 1712 close to Dudley castle in the Black Country.. Later improvements were made by James Watt And Richard Trevithick.

Richard trevithithick made one of the earliest steam locomotives: locomotion. whi cwheels made it so it derailed quite frequently. Robert stevenson made another called the rocket and has taken much credit for the invention of the steam valve but it was the engineer of sans parell timothy hackworth who invented it.

William Symington invented Efficient Steam Navigation. He was a native of Leadhills, Lancashire and Scotland.

V = I x R so 120/96.8 = 1.24 Amps.

To the naked eye - usually not much. To an oscilloscope (and some gadgets) it'll look like a series of pulses. To the appropriate equipment, those pulses can be anything. TV, music, a voice conversation, financial transactions.

Basically each and every amplifier circuit is made up of coupling or use of transistors.

The amplifier amplifies the signals because transistor makes either voltage or current to rise as a result of either of it's regions of operation i.e. open circuit(cut off region) or short circuit (saturation region)

Both the operation regions are not required continuously. Hecne the transistor works in either saturation or cut off regions only when emitter-base junction is forward biased, which can be applied as per requirement.

APPLICATIONS OF TRANSISTOR AND HENCE AMPLIFIERS ARE :

OSCILLATORS, LOUD-SPEAKERS, POWER AMPLIFIERS, VOLTAGE AMPLIFIERS, CURRENT AMPLIFIERS, ANALOG TO DIGITAL CONVERTER, DIGITAL TO ANALOG CONVERTERS

A: NO they are not lost they just stop from flowing from nucleus to nucleus and resume their orbit to maintain balance with the structure of with nucleus

It is analogue as it can have more than one value unlike digital which has two main values which are 1 or 0.

A transformer's capacity is rated in volt amperes(V.A). This is the product of the secondary winding's current rating and voltage rating.

The monolithic integrated circuit was invented by Jack Kilby at Texas Instruments in 1958. It was made of a single crystal of germanium. Although all the components were made together in that crystal their interconnections still had to be wired.

In early 1959 Robert Noyce of Fairchild Semiconductor invented an improved integrated circuit using silicon. The use of silicon instead of germanium allowed passivation of the chip surface with an insulating layer of silicon dioxide and interconnecting the components with a layer of metal over that. These were the first practical monolithic integrated circuits and Kilby's original design never went into production.

Quite simply, it's an amplifier wherein the stages as set up so that the output of one stage is coupled directly into the input of the next stage without any wave shaping or tuninig components between them. This makes for fairly flat frequency response. A link is provided to the Wikipedia article on direct coupling.

A voltage divider (two resistors in series) will achieve the required result. The value of the resistors will depend on what current is required to be supplied. It also matters what variation from 3V is allowed since taking current will make the voltage drop.

An electronics parts shop will sell components to make a more efficient system.

Or you could get 3 voltage regulators .. 9V then 5V then 3V in series .. that should keep the voltage stable as long as the 9V supply is

A typical diode has a band on one end of the diode. That is considered the positive end. Current is considered to flow from the negative end to the positive end. In power diodes, they can be of two types-- positive polarity and negative polarity. Power diodes are usually designed with one end of the diode to be mounted in a heat sink. Since the desire is to allow current to flow in only one direction, the engineering of the circuit determines which way the current is designed to flow, hence the designation of positive or negative diodes especially for power diodes. A typical car alternator has 3 positive diodes and 3 negative diodes for a total of six.

Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).

If you mean how they work then magnetic fields

Induction. Voltage applied to one winding induces a voltage in another winding. The voltage induced is dependent upon the turns ratio between the two windings.

Current is said to be induced in the other winding as well (since a voltage is induced, current will flow if the circuit is complete). Depending on the transformer type, current may flow directly from the series winding (in autotransformers, for example) to the secondary output (conduction, as opposed to induction).
