But, there are no ideal voltage sources, i.e., all real voltage sources have some maximum current delivered into a short circuit. This is modelled by placing a resistor in series with an ideal voltage source and this resistance is the "internal resistance" or "source resistance". Clearly, the maximum current from such a source is:

Using the 2 bulbs in series add an extra battery in series with the first so that their voltages both act in the same direction. Draw the circuit you have created. ... If the batteries have the same voltage the net potential difference across the two batteries is zero; there will be no current. Batteries in series:
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Any number of voltage sources, including batteries, can be connected in series. Two batteries connected in series are shown in Figure 10.31. Using Kirchhoff''s loop rule for the circuit in part (b) gives the result

Connecting batteries in series can achieve a higher current (Amperes) than joining them in parallel. Demerits of connecting batteries series Placing more than two batteries into one device requires more space than using them separately because of their bigger size and resistance to mechanical shocks.

With direct current, the charge flows only in one direction. With alternating current, the charges slosh back and forth, continually reversing direction. The Duracell web site has a nice explanation of how batteries work. Current and Drift velocity. An electric current, which is a flow of charge, occurs when there is a potential difference.
Battery Charger: This represents two voltage sources connected in series with their emfs in opposition. Current flows in the direction of the greater emf and is limited by the sum of the internal resistances. (Note that each emf is represented by script E in the figure. ) A battery charger connected to a battery is an example of such a connection.
Batteries are always used in series with rare exception. Parallel connected batteries are problematic. It does increase max current, but under low current demand the higher output battery tries to charge the other battery. The switch disconnects the batteries from the circuit but the batteries still have a current path between each other.
Notice that in some nodes (like between R 1 and R 2) the current is the same going in as at is coming out.At other nodes (specifically the three-way junction between R 2, R 3, and R 4) the main (blue) current splits into two different ones. That''s the key difference between series and parallel!. Series Circuits Defined. Two components are in series if they share a common node …
The parallel-connected batteries are capable of delivering more current than the series-connected batteries but the current actually delivered will depend on the applied voltage and load resistance. You understand Ohm''s Law, but the "parallel batteries supply more current" statement should really be "parallel batteries CAN supply more current".
