How does the ac generator output is affected by the resistive inductive and capacitive load?

When a resistive AC circuit contains inductance the total opposition to current flow is called?

The resistance of an a.c. load is called 'resistance' (R). Resistance is not affected by frequency, only by the cross-sectional area, length, and resistivity of the conductor. Having said that, because of the skin effect, which causes an a.c. current to flow closer to the surface of the conductor, the effective cross-sectional are is reduced, so the value of a.c resistance is somewhat higher than the d.c. resistance -this difference increases with frequency.The opposition to a.c due to inductive or capacitive loads is called reactance (inductive reactance or capacitive reactance), and the overall opposition to a.c. current is the vector sum of resistance and reactance, and is called impedance. That is:(impedance)2 = (resistance)2 + (reactance)2

What are the factors that affect impedance?

In AC, impedance (Z) takes on real and imaginary components, and so do voltage (V) and current (I). Re(Z) is affected the DC resistance. Im(Z) is determined by the capacitive and inductive components of the circuit.

What is the difference between lagging and leading power factor?

Power factor is the ratio of watts (true power) to VA (volt-amperes, also called apparent power). Where the load is resistive only, the power factor is one, or unity, because the voltage waveform and the current waveform are in phase. Thus, for resistive loads only, true power and VA are the same. Where the load is reactive, the load stores energy, releasing it during a different part of the cycle. This shifts the current waveform so that it is offset, or out of phase with the voltage waveform. Reactive loads can be inductive (electric motors), capacitive, or non-linear (rectifier power supplies). When the load is inductive, the inductance tends to oppose the flow of current, storing energy then releasing it later in the cycle. The current waveform lags behind the voltage waveform. When the load is capacitive, the opposite occurs, and the current waveform leads the voltage waveform. So, lagging vs. leading is another way of saying the net reactance is either inductive or capacitive. This is slightly simplistic, and what we are talking about above is really DPF, or Displacement Power Factor. Non-linear loads don't really shift the current waveform, they distort it. The current waveform starts to look like a square wave, and square waves contain harmonics. So non-linear loads add harmonic distortion, and this tends to mimic a capacitively reactive load, adding some leading power factor. So when we say power factor, we really must include DPF plus harmonic distortion in total. One memory aid that may help to remember all this is: ELI the ICE man The L in ELI means inductance. The E (voltage) comes first, then the I (current) lags behind. Inductive reactance produces a lagging power factor. The C in ICE means capacitance. The I (current) comes first (leads) then the E (voltage) comes later. Capacitive reactance produces a leading power factor. Remember, it's always the current waveform that is affected by the reactive load, so you have to think about whether the current is leading or lagging. Most reactive loads are inductive, so at most sites the PF is lagging. One cool tidbit is that capacitive reactance cancels out inductive reactance. So if we have a building full of motors, we can add a bunch of capacitors to improve our power factor, meaning we get as close to unity as we can. Thus we have power factor correction capacitors that are made just for this purpose.

Who was to blame for the Walkerton tragedy?

Cow manure ran into the rivers which affected the water and the water generator was already broken.

How is the induced voltage of separately excited dc generator affected if the speed increases?

as speed increases, induced voltage increases

How do you change a 220V 50Hz electric water heater to 60Hz 220V?

Not without spending a great deal of money. Appliances with motors and timers at 50 Hz would have to be changed out to 60 Hz components. Appliances that are strictly of a resistive nature will operate without any problem.

What are the factors effect on the value of impedance when connect inductor and resistor in series?

Impedance (expressed in ohms) is the vector sum of a load's resistance and inductive reactance.Resistance is determined by the length, cross-sectional area, and resistivity of the conductor, while the inductive reactance is affected by the inductance of the load and the frequency of the supply.Resistance can also be affected by the 'skin effect' which causes the current to flow towards the surface of a conductor, reducing the effective cross-sectional area of the conductor. This is called 'a.c. resistance', and increases with frequency (at normal mains frequency, a.c. resistance is not markedly greater than d.c. resistance).

Will a 220v 50hz kettle work in 220v 60hz supply?

Look on the appliance's data label. There are many appliances that will allow 50 - 60 Hz operations. Also there should be a 1 -800 number on the back of the operation manual. Call them and ask if the unit can be used on both frequencies.

Is hydroelectric power better for the environment?

Hydroelectric power is better for the environment -- just go to a hydroelectric generator and look for the smoke stacks. There are no mufflers or smoke stacks on a hydro generator. A generator without pollutants emitting to the air has to be better for the environment... for the air. However, ecosystems are sometimes negatively affected by the dams set up to provide hydroelectricity, and therefore there are both positive and negative influences by hydroelectricity. Sure, it can slow down global warming, but if you save the polar bears this way you destroy other aqua life.
