### State the imitation of ohm's law?

imitation of ohms law is that it can be applied only to linear devices it cannot be allowed to non linear devices...

### What is a linear resistor?

which obey ohms law ANSWER: Not all potentiometers are linear some are made to follow a logarithm function some follows an exponential function. A linear potentiometer will have a linear curve. Materials that obey Ohm's Law are called 'linear' or 'ohmic'; those that don't are called 'non-ohmic' or 'non-linear'.

### What observation about the current in a metal conductor was the basis for Ohm's law?

For Ohm's Law to apply to a conductor, the ratio of voltage to current must remain constant for changes in voltage.If the ratio changes when the applied voltage changes, then Ohm's Law does not apply.It's as simple as that!Conductors or devices to which Ohm's Law applies are termed 'linear' or 'ohmic'; those to which Ohm's Law does not apply are termed 'non-linear' or 'non-ohmic'. There are far more non-linear devices than linear devices, from which we can conclude that Ohm's Law is not an universal law.

### 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.

### What are the conditions under which ohm's law is obeyed?

When you are using semi conductors or the conductor is at a very high temperature.AnswerOhm's Law is not a universal law, and only applies to a limited range of conductors. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if the ratio varies, then Ohm's Law does not apply. Materials for which Ohm's Law applies are called 'linear' or 'ohmic'; those for which it doesn't apply are called 'non-linear' or 'non-ohmic'. There are far more 'non-linear' materials than there are 'linear'; these include the metal tungsten, electrolytes, gases, and semiconducting devices, such as diodes, etc.The ratio of voltage to current is termed 'resistance', and applies to both linear and non-linear devices. However, the equation, R = E/I, does NOT represent Ohm's Law; it is derived from the definition of the ohm. This equation applies for both linear and non-linear devices. But, for non-linear devices, it only applies at a particular voltage, as the ratio varies with changes in voltage.

### Is zener diode a linear device?

Zener diode is not a linear device... it is non-linear one. Since linear devices are those devices which have linear characteristics(V-I CHAR.), or follows the Ohm's law i.e. voltage is directly proportional to current. but in case of Zener diode ohm's law fails down. the V-I char. in both forward biased &amp; reverse biased condition is non-linear. So. Zener diode is non-linear device

### Is ohm law true for all conductors?

No. It only applies to a very limited range of conductors that are classified as being 'linear' or 'ohmic'. Most materials are 'non-linear' or 'non-ohmic', and these do NOT obey Ohm's Law. Non-linear conductors include tungsten and non-linear devices include diodes. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if it doesn't, then Ohm's Law doesn't apply. Period!

### 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 true for all conductors?

No. It only applies to a very limited range of conductors that are classified as being 'linear' or 'ohmic'. Most materials are 'non-linear' or 'non-ohmic', and these do NOT obey Ohm's Law. Non-linear conductors include tungsten and non-linear devices include diodes. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage; if it doesn't, then Ohm's Law doesn't apply. Period!

### What are the problems with Ohm's law?

The main problem is that, despite its name, it is not really a 'law'! It applies to very few materials (called 'ohmic' or 'linear' materials). The vast majority of materials (called 'non-ohmic' or 'non-linear') simply do not obey Ohm's 'Law'!

### Why ohms law applicable only linear resister?

because they have a proportional relation
