I really need to know the difference between the two as I have an exam tomorrow D:. What is the difference between the two and how do I calculate each one of them? The book says " IR is the potential difference that is measured across the load resistor R. This is the same as the potential difference that would be measured by a voltmeter connected across the terminals of the supply and is referred to as the terminal potential difference. Termina pd = EMF - Ir"
I = Current
R= Resistance
r= internal resistance
Can someone please word it better or help me out here?
Thank you
