yes
at any particular instant of time
the non linearity is usually time based
so after the capacitors charge and the tubes warm up you have steady state to do the calcs untill something upsets the balance

Can thevenins's theorem be applicable in a network having nonlinear elements?
yesAnswerNo it cannot, any more than Ohm's Law can be applied to circuits with non-linear elements.
Why Kirchhoffs current law and Kirchhoffs voltage law cannot apply on distributed circuits?
Actually, they do apply.Kirchoff's Current Law states that the signed sum of the currents entering a node is zero. This applies whether the node has only two connections, such as in a series cicuit, or more than two connections, such as in a parallel circuit. Some people confuse this with the rule that current at every point in a series circuit is the same. That is just a special case of KCL, but the real rule has to do with the node, and not the circuit.Kirchoff's Voltage Law states that the signed sum of the voltage drops going around a series circuit is zero. This applies for simple series circuits as well as for complex series/parallel circuits. Pick any loop in a circuit and walk around it - you will find that the signed sum of the voltage drops is zero, no matter what.
Why ohms law is not applicable to semiconductor devices?
Actually, Ohm's law is applicable to semiconductor devices.The issue is one of perspective. The semiconductor device does not have a purely resistive response curve, so it would seem that Ohm's law falls apart.Even in the so called linear range, you still have a somewhat non-resistive curve, so there are still limitations.And, of, course, outside of the linear range, beyond the knee point, everything falls apart, so to speak.That said, at any instant of time, a semiconductor device can be perceived as a resistor - yes, one that changes value - but still a resistor - at that point of time. As a result, basic circuit analysis techniques including Ohm's law, Kirchoff's laws, and Norton and Thevanin equivalents still hold true.AnswerOhm's Law DOES NOT apply to most semiconducting devices, because they are not linear or ohmic -that is the ratio of voltage to current doesn't remain constant for variations in voltage. Semiconducting devices, such as diodes, are termed 'non-linear' or 'non-ohmic' because their ratio of voltage to current ratio changes whenever the applied voltage changes. However, in common with ALL circuits and circuit devices, the ratio of voltage to current will always tell you what the resistance happens to be for any particular ratio. The so-called 'Ohm's Law formula' (R = E/I) is actually derived from the definition of the ohm, and NOT from Ohm's Law!
Do the ohm's law applies to all types of electrical circuits?
No. Ohm's Law only applies to linear or ohmic circuits. Ohm' Law is a law of constant proportionality -that is, the ratio of voltage to current must be constant over a wide range of voltage variation. In other words, if you varied the voltage and measured the resulting current, the result would be a linear (straight line) graph. If the resulting graph is not a straight line, then the ratio of voltage to current is not a constant, so Ohm's Law does not apply -such circuits are called 'non-linear' or 'non-ohmic'. Most metal conductors obey Ohm's Law over a reasonably-wide variation in applied voltages, but many don't -for example, tungsten does not obey Ohm's Law. Many electronic circuits, including diodes, etc., are non-linear, as are electrolytes.The equation R = V/R applies in all circumstances -it will always tell you what the circuit's resistance happens to be for that particular ratio of voltage to current. It must be understood that this equation is NOT, as many think, 'the equation for Ohm's Law', but is derived from the definition of the ohm.
Is ohms law is applicable for transmission line?
Ohm's Law is applicable for transmission lines. It is applicable for every case of every circuit in every situation. That's what makes it a law.The "complexity" is that 1.) resistance is not constant, it being a function of temperature and other factors, and 2.) for AC circuits, impedance makes the calculation complex.AnswerOhm's Law is not a universal law, and applies in very few cases and, then, only to linear or ohmic devices. It certainly doesn't apply 'to every case, of every circuit, in every situation', and many physicists believe that it should not be classified as a 'law'.If, on the other hand, you are referring to the equation, R = V/R (for d.c.) or R = V/Z (for a.c.) then, yes, these do apply to transmission lines. But you should be aware that these equations are not derived from Ohm's Law!
Does Kirchhoff law applicable to linear circuits?
Yes, Kirchhoff law is applicable to linear circuits. In fact, both of Kirchhoff'slaws are applicable to ALL circuits, because they're just conservation laws.
Is ohm's law applicable to high transmission lines?
Ohm's law is applicable to all electrical circuits.
Can thevenins's theorem be applicable in a network having nonlinear elements?
yesAnswerNo it cannot, any more than Ohm's Law can be applied to circuits with non-linear elements.
Why ohm's law is not applicable in complex network?
Because Ohm's Law is only applicable on good conductor which shows linear relationship b/w voltage and resistance while in the semi conductors it shows non linear relationship, that's why Ohm's law is not applicable on semi conductors...
Is ohms law applicable to both ac and dc?
Ohm's law is applicable to any circuit, be it DC or be it AC.AnswerOhm's Law is applicable to all linear or ohmiccircuits, regardless of whether they are d.c. or a.c. A linear or ohmic circuit is one in which the ratio of voltage to current is constant for variations in voltage. Ohm's Law does not apply to non-linear or non-ohmic circuits (e.g. tungsten, electronic devices such as diodes, and electrolytes).
Why ohms law applicable only linear resister?
because they have a proportional relation
Ohms law is applicable to linear circuit means what?
You cannot apply ohm's law to non-linear devices. This is because, the non-linearity introduces different V-I characteristics which cannot be answered by mere Ohm's law.
Why Kirchhoffs current law and Kirchhoffs voltage law cannot apply on distributed circuits?

What is Ohm's law in a direct circuit?
Ohm's Law is a law of constant proportionality, and only applies to circuits in which the ratio of voltage to current is a constant over variations in applied voltage. Such circuits are called linear or ohmic circuits, and include most metals. However, in the case of metals such as tungsten, for electronic devices such as diodes, and for electrolytes, Ohm's Law does NOT apply, and we call such circuits 'non-linear' or 'non-ohmic'. For linear circuits, Ohm's Law simply states that the current flowing through that circuit is directly proportional to the voltage applied across its ends. The equation R = V/I is not, as many think, derived from Ohm's Law, but from the definition of the ohm.
Can Norton's theorem be applied to network which contains non linear resistance?
yesAnswerNo it cannot, any more than Ohm's Law can be applied to circuits with non-linear elements.
Why ohm's law is not applicable in networks?
Ohm's Law: Volage = Current times Resistance Yes, voltage is proportional to current. That applies in simple circuits as well as to complex circuits such as electrical networks. Your statement that "voltage is inversely proportional to current in electrical circuits" is incorrect. Perhaps you are not considering some critical part of the statement, or you simply heard it wrong.
Why does A.C. not follow OHM's law?
Resistors in A.C circuits completely, absolutely and totally follow ohms law. Ohm's law is followed by resistances and has nothing to with the alternating or direct nature of current. Ohm's law is however not followed by non linear loads. Also, in A.C systems we generally write V=I*Z which is analogous to V=I*R in D.C circuits. For capacitive and inductive circuits the current magnitude varies in accordance with the circuit impedance but there is a phase shift corresponding to the lagging/ leading nature of current. Conclusion: it's absolutely wrong to say that ohm's law is not followed in A.C. Its as much applicable to AC systems as to DC systems.
