Q. Ohm’s law is not applicable to

A
DC circuits
B
High currents
C
Small resistors
D
Semi-conductors.
Solution:

The main applications of Ohm’s law are:

  • To determine the voltage, resistance or current of an electric circuit.
  • Ohm’s law is used to maintain the desired voltage drop across the electronic components.
  • Ohm’s law is also used in DC ammeter and other DC shunts to divert the current
    Ohm’s law is also not applicable to non ? linear elements. Non-linear elements are those which do not have current exactly proportional to the applied voltage that means the resistance value of those elements changes for different values of voltage and current.
