Why should electrolytic capacitors not to be used in AC circuits?
Electrolytic caps are polorized and are used for filtering and will charge up to a DC value as in power supplies.
Why coupling capacitor block DC in amplifier?
capacitors at input block dc and allows ac only. so absolute none of the dc enters the circuit. They are called decoupling capacitors or blocking caps. -DANNY S
What is the effect of leading power factor on transformer?
that is to reduce the cost of the power plant.... Improving power factor(increasing the ration active/apparant power morethan 0.8) will increase the efficiency of uer system. Improving power factor denotes eleminating the recative power(which do no average work).... If u have more capacitive parts in uer system, the power you may need be really high when the capacitor is charging. But as it is in an a.c. system, used energy will be released and hence the average energy consumption of the cap is null. As in one instance iot absorbes energy, the electricity distributers must be able to generate such an high power which will incrrease their cost(eventhough the absorbed energy will be released)!!! Just by reducing the the reactive power, you can reduce the enery absorption. However to do so, you may have to use caps/inductors whcich will cost you a lot. Generally, electricity distributors say, "You must not reduce uer power factor than 0.8"... In some countries, distributors pay for the factries if there power factor is higher than a cirtain value(0.95).... -R-
Is there a difference between the yellow and red electrical caps?
No,the purpose is to demonstrate which wires are hot and which aren't.That way if someone comes along in three or four years they don't have to guess.
How do you replace the wire on an old fashioned fuse?
You do not replace the wire - you replace the fuse as a whole unit. Never try to "get by" with anything but the correct fuse - it is asking for a fire if you don't. If you have the old style which have screw on caps, you remove the caps and replace the fuse with the exact fuse material that is identical to the one that burned. Reinstall the caps tight and re-insert the fuse. These types of fuses are becoming obsolete and can be hard to find the fuse material for them. You can replace the fuse with a newer fuse rated for the same amperage as the old one. Note, however, that this type of fuse is higher amperage - 30 amps or above. The type of fuse described at the beginning of this answer - the old "screw in" type - is not fixable - it must be replaced outright

What is mars axis poles look like?
The mars axis poles have ice caps, which is frozen water on mars.
On mars where are the polar ice caps locted?
North and South poles.
What are the white patches at the poles of Mars?
The white patches at the poles of Mars are the planet's permanent polar ice caps. Like Earth, Mars has ice at its poles.
What makes up surface on mars?
Rocks covered with Iron Oxide or rust and this is the reason why it is called a red planet.Mars have also ice caps on North and South poles.

No,there not
