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...
Yes, Ohms law is applicable in altering current.
because they have a proportional relation
Absolutely
Ohm's Law is applicable in every case, even in cases of non linear resistance such as diodes and light bulbs, and in reactive cases such as motors in AC operation. It just becomes more complex (no pun intended) to calculate effective resistance.
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
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.
ohms law.
To find the conductance using ohms law,you take the inverse of the resistance(/R)
Current
no
No.
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
