Potential Difference and EMF (Grade 10 NSC Matric Physical Sciences): Flashcards

Driving force pushing charges around circuit

$\frac{W}{Q}$ (work per unit charge)

1 joule per coulomb ($1\text{ V} = 1\text{ J/C}$)

Potential difference between two points

In parallel across component

Maximum potential difference when not in complete circuit

When no current flows

Terminal PD less than EMF

Maximum capability

6 joules
