What are the disadvantages of using the thevenin theorem?
Thevenin's theorem is only valid for linear and bilateral networks.Practically, linearity of any circuit is over a certain range.Hence it is only valid for certain range.
What are the disadvantages of leading power factor on generator supply system?
in case of leading power factor the air gap flux inside the alternator will increase which may cause over heating of the stator end coil and overhang portions.
What are the advantages and disadvantages of JFET over BJT?
An advantage of JFET is stable high current operation. A disadvantage of JFET is low capacitance. An advantage of BJT is constant voltage operation. A disadvantage of BJT is low thermal conductance.
What is the advantages and disadvantages of varactor diode?
is basically an electrically controlled variable capacitor no moving parts need a monitored voltage source to hold the value temperature sensitive Si based dont work over 100C variable capacitors in the mechanical adjusted variety work with higher voltages arent voltage spike sensitive and are far more rugged are in picofarad to micro farad range can handle many kilowatts set and forget dont need controls to maintain capacitance arent temperature sensitive can be motor driven for electric control
What are the disadvantages of series capacitors in transmission lines?
The series capacitors can be the cause of overcompensating on the power line and thus cause the following problems:- a) Over voltages on the line when connected loads are smaller than the rated loads and this can damage the transformers and capacitors b) Ferro-resonace phenomenon can cause very high volatges again can be damaging c) The fault level of the poweer system will increase and if not considered in the design, the fault current could exceed thedesign limits.
What are the differences between broadband and baseband?
Baseband Signalling: 1)Uses digital signalling 2)No frequency-division multiplexing 3) Bi-directional transmission 4)Signal travels over short distances Broadband Signalling: 1)Uses analog signalling 2)Unidirectional transmission 3)Frequency-division multiplexing is possible 4)Signal can travel over long distances before being attenuated
What is the disadvantages of tomato?

When you are driving and realize you have a flat tire you should?
Calmly pull over into a safe place (signalling) and if safe to do so, jack up the car and change the wheel with the spare.
What are the advantages and disadvantages of voice over IP?
It has all the advantages from cost efficient to speed efficiency. Disadvantages? Power dependent.

What are the advantages and disadvantages of a covered wagon?
the disadvantages are that many people died over diseases and sometimes the wagon broke to the cause of the hills
Give some Areas of application of coaxial cables?
Coaxial cable (multiple cables with a common axis) is widely used for signalling as the outer cable acts as a screen for the inner cables. Coax is ideal for short/medium distance signals - it's easy to interface to, and cheap. For longer distance, it has some disadvantages - the signal starts to decay over distance and repeaters have to be used to reamplify the signal.
