19-06-21 (Importance of Ohm's Law)

 Ohm's Law According to   ElectroMagnetic Field Theory (EMFT):-
 The current density in linear conductor is   proportional to the electric field intensity,     when temperature is constant.

 Importance of Ohm's Law:-

 
         
              Voltage (V)=2V

              Current (I)=20mA➡0.02A

              Total Voltage (Vᴛ)=9V➡Vᴛ - V=9-2= 7V

              Resistance (R)=?
  
           Resistance(R)=V/I= 7/0.02= 350Ω
