Basically it looks like this: The voltage in the wire (or power plant) is high and the resistances of the wires are low, so you think that the current should be high. Right, but now consider that the receiver has a very high resistance. This is what makes the current in this circuit low.
Due to their higher energy density, high voltage batteries can be designed to be smaller and lighter than their low voltage counterparts. This compactness is advantageous in applications where space is limited. 3. Longer Range
Now remember, that a model for a battery is an ideal voltage source, internal resistance. when you start pulling current from the battery and complete the load there will be a voltage drop rI corresponding to the voltage drop due to the internal resistance this will cause the voltage of the cell to be lower than the voltage of the voltage source.
If you increase the load on a battery (decrease load resistance, add more light bulbs in parallel...) the current delivered by the battery will increase, causing an increased voltage drop across the battery's internal resistance and reducing the voltage measured between the battery terminals. This graph does not relate to the battery being used up.
Eventually, with a shorted out battery the current taken is at maximum but the terminal voltage is zero. The internal resistance of the cell causes this to happen. If a cell didn't have internal resistance it could supply any amount of current without the terminal voltage falling (an impossibility of course).
Check to see the reading and if it is over 12.9 volts, your battery may have excessive voltage. 12.6 to 12.8 is the ideal voltage level for your battery. Anything lower than that is a completely different set of problems. Also Read: Why Do Car Batteries Corrode
