There is internal resistance in a battery because a battery is not an ideal voltage source. It may be close, but it is not ideal. As a result, analytically, there will be some series resistance, resistance which places a limit on the maximum current that the battery can provide.
While no battery is ideal, most are sufficiently ideal to not require any consideration of the internal resistance. If your circuit is dependent on the internal resistance of a battery, then it is probably not well suited for that application.
What else can I help you with?
Is it desirable for a battery to have a high internal resistance?
No, it is desirable for a battery to have a low internal resistance.
Actual internal resistance of 1.5 volt battery?
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
A 19 V battery delivers 114 mA of current when connected to a 72 resistor. Determine the internal resistance of the battery.?
Internal resistance is approximately equal to 94.667
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
The Storage battery of a car has an emf of 12 volt if the internal resistance of the battery is 0.4 resistance what is the maximum current that can be drawn from the battery?
You have to imagine the internal resistance as being in parallel with any load you connect. You get the maximum possible current when the load is zero. In this case, just apply Ohm's Law. That is, divide the voltage by the internal resistance.
Is it desirable for a battery to have a high internal resistance?
No, it is desirable for a battery to have a low internal resistance.
Actual internal resistance of 1.5 volt battery?
The value of internal resistance of 1.5 volt battery is 0.5 ohms.
What information does the battery internal resistance chart provide?
The battery internal resistance chart provides data on how much resistance the battery has to the flow of electricity within it. This information can help determine the battery's efficiency and performance.
Does a battery have some internal resistance?
Yes
Can increasing temperature cause internal resistance to increase in a battery?
Yes, increasing temperature can cause the internal resistance of a battery to increase. This is because higher temperatures can lead to material degradation and changes in chemical reactions within the battery, which can ultimately result in higher internal resistance.

If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
The Storage battery of a car has an emf of 12 volt if the internal resistance of the battery is 0.4 resistance what is the maximum current that can be drawn from the battery?
You have to imagine the internal resistance as being in parallel with any load you connect. You get the maximum possible current when the load is zero. In this case, just apply Ohm's Law. That is, divide the voltage by the internal resistance.
When does Internal resistance equals external resistance?
If Rin = Rout, then the voltage at the output of the device goes down to half of the value that the circuit has without the external resistance. Scroll down to related links and look at "Interconnection of two audio units".
If a 12v car battery has 0.04ohm internal resistance what is the battery terminal voltage when the battery delivers 40A?
011.1
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
