The internal resistance of a battery gradually increases as it is used. The power from a battery comes from the chemical reaction between the electrolytes and the electrodes. However, over a long period of time, the chemical reaction will slow down due to rust and corrosion inside the electrodes. As the chemical reaction slows down, the ...
Most circuits have more than one component, called a resistor that limits the flow of charge in the circuit. A measure of this limit on charge flow is called resistance.The simplest combinations of resistors are the series and parallel connections illustrated in Figure 1.The total resistance of a combination of resistors depends on both their individual values and how they are connected.

Connecting batteries of different amp hour ratings in series. In theory a 6 volt 3 Ah battery and a 6 volt 5 Ah battery connected in series would give a supply of 12 volts 3 Ah (the capacity of the weaker battery always restricts the circuit) and if you did so it would work and nothing would explode (to start with).
