Question

The potential difference across the terminals of a battery with an internal resistance of 0.5 Ohms in a closed and open circuit are 8.5 V and 12.0V, respectively. How much current is flowing when the circuit is closed?

Answer 1

given quantities:

$R = 0.5 \Omega$

$U_c=12V$

$I = \large\frac{U_c}{R}$ $=24A$
