10 cards from this deck
Total potential difference when no current flows
Resistance within the battery itself
Actual potential difference when current flows
External resistance in the circuit
ε=V+Ir\varepsilon = V + Irε=V+Ir
V=ε−IrV = \varepsilon - IrV=ε−Ir
Terminal voltage is always less than EMF
Ic=εrI_c = \frac{\varepsilon}{r}Ic=rε
EMF (ε\varepsilonε)
Negative internal resistance (−r-r−r)
