- - - - WE PAY THE BILL OF THE ENERGY
      - WHAT IN I UNIT IN JOULES
      - WHAT DOSE THE WATT AND THE VOLTAGE ON ELECTRICAL APPLIENCES MEANS
      - ENERGY CONSUMED BY A RESISTANCE
        
        FORMULA AND DERIVATION :question:
        
        FORMULA WHEN I IS CHANGING AS A FUNCTION OF TIME
        :question:
        
        FORMULA WHEN V IS CHANGING AS A FUNCTION OF TIME
        :question:
        
        PROBLEMS ON FINDING HEAT IS EACH RESISTOR
        
        BULB PROBLEMS
        
        FINDING THEIR RESISTANCE FROM THE WATTAGE
        
        THERE COMBINATION AND FINDING CURRENT IS SAME AS THAT OF RESISTANCE JUST FIND THE RESISTANC OF THEM AND DO IT THEN FIND WHATEVER YOU WANT
        
        IN REALITY THEY ARE JUST RESISTANCE WHICH RADATE THE LOST ENERGY IN LIGHT
        
        ANY OTHER ELECTRICAL APPLIENCE CAN BE PLACE AS A SUBTUTE TO IT AND SAME
- - - - BATTERY
        
        it is a man which produces a constant electric field in the conductor
        
        it supplues energy by moving the positrons from lower to higher potential
        
        some of this is lost in internal resistance which will be studyed further
        
        when potental is applyed the charges start moving under a constant force
        
        there movement can be suptuded for an army and the velocity is constant
        
        thisis due to the collisions
        
        DRRIFT VELOCITY
        
        this constant velocity is the drift velocity

  - - - WHEN THE L AND A ARE CONSTANT
        
        JUST GET THE INSIGHT OF THE L AND A AND SOLVE
        
        L IS IN THE DIRECTION OF THE CURRENT
      - WHEN L IS VARYING
        
        TAKE DR RESISTANCE
        
        ALL THE DR RESISTANCE ARE IN PARALLEL
        
        INTIGRATE TO GET THE ANSWER
      - WHEN A IS VARYING
        
        TAKE ELAMENT OF DR RESISTANCE
        
        ALL THESE DR RESISTANCE ARE IS SERESE
        
        INTIGRATE THIS TO GET THE ANSWER
      - WHEN TEMPRATURE IS VARYING
        
        DERIVATION AND FORMULA WHEN :question:
        
        COFFICENT OF TERMAL RESISTANCE IS CONST AND TEMPRATURE DIFF IS LESS
        
        TEMPRATURE DIFFRENCE IS LARGE
        
        COFFICENT OF THERMAL RESISTANCE IS VARYING
