What is meant by the term capacitive resistance?
That term to me is incorrect it should be capacitance impedance. Resistance is linear impedance. CAPACITANCE will follow a vector caused by the capacitor value.
How do you build a simple timer circuit?
Timing is complicated in electronics, and there are only a few good solutions. You should use a microprocessor called the LM555 timer (or just the 555 timer). While seemingly daunting at first, this small 8-pin device affords a lot of features and can perform one-shot timing (press a button and keep a light on for a certain time determined by the resistors and capacitors), astable timing (essentially generating an on and off signal), bistable timing (controlling two lights; one on and one stage, and one on at another stage), and with some clever 'hacking' it can be used to encode an analog signal into a PCM (pulse-code modulation) signal, often used for devices such as remote controls and toy aircraft. A quick overview: There are the pins 4 and 8 which should be powered. When you use pins, you count from the bottom left, which is indicated by the small indented circle in the chip. Pin 1 should be connected to the negative end of the battery or power supply. The chip can run from 2 volts to up to 14 (some chips support 18) volts but for something like an LED, 9 volts should be good (a different voltage would mean you'd need a different resistor for the LED). Pin 5, optionally, should be connected through a small capacitor (100nF or near) to the negative end of the battery; the capacitor should not be electrolytic. This is optional as it just helps settle the value on one of the internal comparators and makes the timing more accurate. Pin 7 should be connected through a 10k resistor to positive. Pin 6 should be connected to pin 7. At the end of this series, you should connect a capacitor, which determines the timing amount (as well as the resistor). The second capacitor should be about 100 to 220 uF, which will give you a range of 1.1 seconds to 2.42 seconds. You can of course adjust to any value suited. Pin 2 is the trigger. A 10k resistor should be wired though a push-to-make switch, connected to the negative end of the battery. Then, the positive end of the push-to-make should be wired into pin 2. Pin 3, the last pin, is the output. Wire a 330 ohm resistor and a green LED into this and you are set. Wire the end of the LED to ground (the negative end). Press the button, and it should work, timing for the value of the capacitor. The formula for the time is T=1.1(CR) where C is the timing capacitors' value (C being in farads, and it will be very small), and R being the resistor connected, in ohms. This will be the larger value. The 1.1 multiplication is just because of how the timer works. The whole circuit can be build on a breadboard/prototyping board. Or, if you have the skills, you can build it on a printed circuit board. It should be noted however, this timer is not 100% accurate. Because of component tolerances, you should allow for as much as 17.5% inaccuracy in both directions. If you need more accuracy, you need to get into the very complicated world of quartz crystals, real-time clocks and the like; and even they suffer from 'clock drift' (being incorrect by up to 30 seconds a month depending on temperature). In short, if you need accurate timing, you need an atomic clock! There are many resources on the web for how to do this. Simply use Google or your favourite search engine to search for '555 timer'.
Why ups rating is in kva?
The kva rating includes the power factor of the connected load.KW * Power Factor = kva.AnswerThe above answer is incorrect, as it's actually kV.A x power factor = kW.The answer is straightforward, the output of the UPS is the product of its rated output voltage and its rated output current, and the product of voltage and current is 'apparent power', expressed in volt amperes.

1 For a parallel plate capacitor which is being charged out What the incorrect statement is?
Energy stored in the capacitor does not enter it through the connecting wire through the space around the wires and plates of capacitor.
How do you know if a capacitor is good or not?
You test it.For electrolytic capacitors, it's sometimes (but not always) obvious simply by looking at it that there is a problem; if the capacitor bulges or is actually ruptured, that's a pretty good indication that it might be bad. However, the only way to know for certain is to check it to see if it has the proper capacitance.For various reasons it's difficult to test the capacitance of a capacitor which is in a circuit; you'll usually need to detach it and test it in isolation. It is possible to check the equivalent series resistance of a capacitor without removing it from the circuit, and in some cases this may be enough (a correct ESR doesn't necessarily mean the capacitor is good, but an incorrect one means that it's bad).

Modem won't light up send when wireless router connected?
A modem's send light may not light up when connected to a wireless router if the two are not communicating. This can be caused by a faulty cable, an incorrect configuration, or a bad router.
