Hey,
My question isn't exactly a problem,it's just a doubt which occurred in my mind,while studying current electricity.The potential difference across the emf of an ideal battery is considered to be constant,whereas if the battery has an internal resistance (the case for all real life batteries),the potential difference across it's terminals changes as soon as a current flows through it.
What is the exact reason for this??
