A battery of internal resistance 2Ω is connected to a variable resistor whose value can vary from 4Ω to 10Ω. The resistance is initially set at 4Ω. If the resistance is now increased then, which of the statement is not correct.
  • a)
    power consumed by it may increase or may decrease 
  • b)
    power consumed by it will decrease 
  • c)
    power consumed will first increase then decrease. 
  • d)
    power consumed by it will increase
Correct answer is option 'A,C,D'. Can you explain this answer?
