Electric Circuits (Grade 12 NSC Matric Physical Sciences): Quizzes

Real batteries have internal resistance

Total potential difference when no current

Materials the battery is made from

Terminal voltage is less than EMF

$\varepsilon = V + Ir$

Terminal voltage decreases

$I_c = \frac{\varepsilon}{r}$

$0.50 \, \Omega$

EMF of the battery

$V = \varepsilon - Ir$
