A normal source of emf has some internal resistancerinside it, between its terminals. If a is the + terminal and b is the - terminal, the potential difference, or terminal voltage, between them is Vah. When a source of emf delivers energy to an external circuit, current leaves the + terminal and returns through the - terminal. The terminal voltage is less than the emf because of the voltage drop across the internal resistance of the source internal r Hil ww a Vob =ɛ- ir (when the current leaves the + terminal) Vob =E+ ir (when the current enters the+ terminal) A car battery has an emf of 12.0V and an internal resistance of 0.02 Q.
