Question

A $10 V o l t s$ battery of internal resistance one ohm is connected to a $20 V o l t$ battery of internal resistance $2 o h m$ . The combination is put across a resistance of $30 o h m$ . Find the current through each battery.

Solution

$i = V / R = \frac{20 + 10}{32 + 1} = \frac{30}{33} A m p$
