Can a HIV negative person be a carrier?
No
Why value of hall coefficient is negative?
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
Can HIV negative off spring be carriers?
A HIV negative person can not be a carrier of HIV.
How would you distinguish between an incubatory carrier and a chronic carrier of typhoid fever?
Widal test is negative in incubatory carrier. Widal test is always positive in chronic carrier.
Can O positive and an A positive make O negative baby?
A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
What are negative yards?
In football negative yards are yards lost which happens if the ball carrier is tackled behind the line of scrimmage.
Why is the negative peak of the carrier wave discarded by a diode in demodulation?
It's caused by the action of the diode. A diode conducts when its anode is positive to its cathode, or... when its cathode is negative to its anode. The above statements are saying the same thing. You circuit is applying the carrier wave to the anode, and taking output from the cathode. The diode will conduct and pass the positive peaks of the carrier from its anode to its cathode and through to the load (next component/s after the diode), but diode action will not permit conduction any time when the carrrier wave swings into negative voltage on the anode. You *could* turn the dioe around - then you would get only the *negative* peaks of the carrier wave passing through to the load.
Why is the intelligence signal not in the AM envelope?
The intelligence signal is in the AM envelope.In AM modulation, the carrier is amplitude modulated by the signal. This signal appears as the envelope of the carrier. You can demodulate it by following the peaks on each cycle of the carrier. You can either follow the positive peaks or the negative peaks - it does not matter if the original modulation is symmetrical.
What types of audiovideo cable includes not only carriers for both positive and negative signals but also a grounding carrier?
Balanced
What are the electrons?
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.(:
