What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
What happens when a magnetic material is magnetised?
non-magnetic :)
What happens if positive feedback increases in amplifier?
The gain increases.
What happens when something is demagnetized?
It's no longer magnetic
What is resistance start capacitor run?
most capacitors will measure infinite resistancestarting capacitors are used to set up a rotating magnetic field by phase shifting a coil in a single phase motorwhen the motor gets up to speed a centrifugal switch will disconnect the capacitorthis happens at a random time and can leave the capacitor with a charge easily 4x the applied ac voltage (+/-1,000V)so some capacitors rated as starting capacitors will have an internal bleeding resistorGas discharge lamp ballast capacitors sometimes have discharge resistors.Microwave ovens have capacitors usually in a voltage doubling configuration(+/-20,000V) most have an internal bleeding resistor.Never rely on this resistor being intact or even present.It can have fatal consequences.the internal resistors are sized to discharge the capacitors in tens of minutesTc = R * C ( seconds = ohms * farads )
Why we use blocking and by pass capacitor in CE amplifier?
As the DC component in the signals are not required to be amplified, rather not required at times. Thus a blocking capacitor blocks this DC component from.entering the amplifier. Bypass capacitors are used at the emitter end so that the AC signal reaching the emitter end does not alter the biasing required to maintain the Q-point. All the above happens using the basic characteristic of a capacitor, that it blocks DC and passes AC.
What happens when the magnetic field or or more magnets overlap?
they combine and become one magnetic field
What happens to the magnetic forces as the distance between two magnetic poles decreases?
It remains constant
What happens to the magnetic force as the distance between two magnetic poles decreases?
It remains constant
What happens to capacitors that are connected in series?
The total capacitance from capacitors that are connected in series are added up inversely; 1/Ctotal = 1/C1 + 1/C2 + ... + 1/Cn, where Cn is the capacitance of the nth capacitor.
Why does the sun have spots?
It happens due to magnetic activity.
What happens to the magnetic orientation of rocks as the poles?
There is nothing -_-
