Small resistance inside real batteries opposing current flow
rrr
Max potential difference when no current flows
ε=V+Ir\varepsilon = V + Irε=V+Ir
P=I2rP = I^2rP=I2r
EMF is always ≥ terminal voltage
Series resistor with the EMF source
Greater voltage drop across internal resistance
Measures unknown resistance precisely
Rx=R2×R3R1R_x = \frac{R_2 \times R_3}{R_1}Rx=R1R2×R3
