Electronics Engineering

Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range.

it is also use in agriculture......

it is used to diagnose different diseases

As the question didn't say whether the resistors were in series of parallel, perhaps both eventualities should be looked at. In series, the total resistance is the sum of the series resistors. The 30-ohm and 60-ohm resistors sum to 90 ohms. Total current will be voltage divided by resistance. The 220 volts applied divided by the 90 ohms will give 2.44 amps (2 4/9ths amps). In parallel, each resistor is connected indendently across the 220-volt source. Each one will "feel" the 220 volts and draw current accordingly. Since current equals voltage divided by resistance (just like always), we have to make the calculation for each resistor. The 220 divided by 30 equals 7.33 amps (7 1/3 amps). The 220 divided by 60 equals 3.66 amps (3 2/3 amps). The two branch currents each represent a part of the total circuit current, we have to find the sum of the branch currents to find the total current. Our 7.33 plus 3.66 amps sums to 11 amps.

Psoc includes the analog and digital component where else in controller only digital. :P

you use an plastic container because it is best to use when doing an egg drop experiment

Bias is some personal preference which interferes with fairness or objectivity. For example, I might have a bias in favor of men over women, so when I am hiring new employees I hire only men. Or I might have a bias in favor of my own ethnic group. Or I might be biased in favor of tall people and against short people.

Positive feedback

A frequency converter converts alternating current of one frequency to alternating current of another frequency.

Generally it's used for controlling the ac motor speed by changing the supply frequency.

If you have 14 watts, you have 14 watts of power. We measure electromotive force (EMF), which is commonly called voltage, in volts. EMF (voltage) is the force that will drive electron current flow, which is measured in amps. Simply put, power is current times voltage, or, said another way, watts is amps times volts. If you have 14 watts, you could have 14 amps at 1 volt, 7 amps at 2 volts, 2 amps at 7 volts, or any other combination of current and voltage with a product of 14. You may have picked up that because watts is amps times volts, we can say that a watt is a volt-amp. Extending that thinking, 14 watts is 14 volt-amps. There is no way to write 14 watts in volts, at least not without having a bit more information.

Whoa.... Please rethink your question and ask it differently because:

North America uses 60 Hz at 120 or 240 Volts power. Normally 120 volts in hotel rooms and home living areas; normally 240 volts for an electric kitchen stove.

Europe, Asia & Australia use 50 Hz at 240 Volts power. Everywhere.

Both 50 Hertz (Hz) and 60 Hz refer to the number of cycles for Alternating Current (AC) as opposed to zero cycles in Direct Current (DC). Flashlights and automobiles work off their DC battery.

There is a historical reason why North America and Europe use different cycle (hertz) systems but for the traveller this is what you should know:

1) A 120 volt electronic device will blow up or smoke or melt if plugged into a 240 volt system.

2) A 240 volt electronic device will either run slow or not at all if plugged into a 120 volt system.

3) Most countries have their own style electronic plug to match a wall socket (mains) so the chances of YOUR device matching the visited country's wall socket is not promised.

4) Many devices such as modern laptop computers have dual-voltage/dual cycle power adapters that allow them to be used world-wide. Some devices such as modern hair dryers have a switch in the handle allowing the user to choose between 120V or 240V.

5) 120V is sometimes called 110V and 240V is sometimes called 220V - as a traveller you really don't care about terminology and it makes no difference to you or your electronic device(s).

Basically, your series and shunt ohmmeters differ in circuit configuration. Your series ohmmeter is configured in a way that your "meter" (which has internal resistance) is connected in series to your "measured resistor" and we all know that those TWO resistances will ADD up causing some sort of inaccuracy. While on the other hand, your shunt ohmmeter is configured in a way wherein your "meter" is connected in PARALLEL to your "measured resistor" that will ease-up the inaccuracy but will only measure resistances ranging from 200 Ohms to 400 Ohms (typically and depending on your configuration).

Resistance is like frictional force. It opposes flow of electricity. So this will consume some electricity in the form of heat. Measured (in Ohm) Inductance (in Henry) nd capacitance (in farad) stores energy in their electromagnetic nd electrostatic fields respectively. They don't consume any power. But in real scenarios due to the element's internal resistances used in design they usually have a drop. But these two have important spot in engineering. Both of them effects the powerfactor in the circuits.

P = IV V = P/I V = 5.00 W / 5.0 A V = 1.0 V Therefore 1.0 V is consumed by the resister

The voltage drop is equal to the total resistance across which it is dropped multiplied by the current flowing through this resistance.

i.e. V=IR (where V is the voltage drop, I is the current and R is the resistance)

Thus, I=V/R

So I=5/1000 A = 5*10-3 A = 5 mA

So the current flowing through your circuit is 5mA. Note that this answer is theoretical, and that it may differ from what you observe in practice due to component tolerances (resistors with the gold band at the end are only accurate to within 10%).

at thebeginning of electronic technology the vacuum tube was used in electronic circuit. .but now a days semiconductors are used in electronic circuit

Ohm's law relates voltage, current, and resistance.

Voltage is current times resistance

Current is voltage divided by resistance

Resistance is voltage divided by current

A galvanic isolator is a device which blocks low voltage DC currents coming on board a boat. The reason why these currents are blocked, they cause corrosion to metal underwater.

area of the conductor, length of the conductor and temperature around the conductor..........

The simplest way to understand it is to use Ohm's law: E = IR. Voltage (E) can be though of as pressure that drives the current. Voltage is measured in volts. Current (I) can be thought of as the actual flow of electrons within the circuit. Current is measured in amperes, or amps. Resistance (R) can be thought of as exactly that - the amount of opposition to current flow in a circuit or component. Resistance is measured in ohms. So let's see how this works. E = IR. If E is constant (typical for a battery) then the current (I) is equal to the voltage divided by the resistance. Let's use a voltage of 12 volts, and a resistance of 2 ohms. The current is I = 12 volts/2 ohms= 6 amps. If you remember Ohms law, you can predict what will happen in simple circuits using only a little bit of simple algebra. What is arguably the simplest form of this relationship is that a 1 volt source connected to a 1 ohm resistor will cause 1 amp of current to flow. There are other ways to say the same thing. A 1 ohm resistor with 1 amp of current flowing through it must be connected to a 1 volt source. A 1 volt source that causes 1 amp of current flow must be connected to a 1 ohm resistance.

No. By definition, a parallel circuit occurs when there is more than one alternative path.
