we say motor consumes power or energy in contrast with transformer,that transformer does not consume power it utilisese it. While motor which works on the same principle of transformer consumes power.This is because in motor work is to be done to rotate the rotor so that much amount of energy...
try by changing mode of operation and operating frequency
for higher capacitance prefer lower frequency while for lower capacitance prefer higher frequency..
hey i don't now how to post so i am asking here.
I was confused actually how a transistor can provide gain. as we know that energy can not be created.so from where this extra energy is coming.
I know that dc sources used in baiseing are providing this energy.
but how it is happening.
waiting for...
As everybody said , nuclear reaction is not combustion reaction.A combustion reaction requires oxygen to carryout reaction,in nuclear reaction nucleons participate,either they combine or split into two nucleons which result in release of large amount of energy causing explosion.Sun is one of the...
moon is bound in its orbit due to Earth's gravity .It is revolving around Earth since there is no external force to stop it ,so even Earth stops rotation moon will continue its revolution until any external force stop it .
it can be like this.
initial velocity=0
velocity at the end of 3 sec is100/9.77m/s i.e. 10.23m/s
now acc. = (final vel. - initial vel.)/time=(10.23-0)/3=3.41m/sec.sq
so,acc. after 3 sec is 3.41m/sec.sq
when a semiconducter is doped with phosphorus atom containing 5 electron in its outermost shell.Then its 4 electrons are bonded with si atom & one electron left free .This electron is not bonded to any atom so on supply of energy =1.1ev it gets out from the in fluence of pho.atom ,in case of p...
yes ,when covalent bond breaks then electron leave its place from the bond & thus creat a hole there in this manner when one bond break up then a pair of hole& electron is generated.
the reason can be that ,when u completely fill the coil with the bar there is no change in magnetic flux in the coil &so no current is induced in the coil & thus coil is not heat up but when u stick the magnet in half of the coil flux in the coil varies & current is induced resulting in heating...
in reverse biasing when we apply high reverse voltage then ,electron in the diode bonded by covalent bond gets free due to the brockage of covalent bond & breakdown ocures.the covalent bond are broke up due to the high electric field across the junction,the break down voltage depend on the...
u can find the force of friction on the three different surfaces by knowing the cofficient of friction of the three surfaces and finding the weight of the ball & apply the formula.
