One of the main reasons that battery voltage dropping under load is because the current passing through the battery causes resistance. This resistance creates heat, which in turn reduces the battery’s ability to deliver power. Additionally, as a battery discharges, its internal resistance increases, which also contributes to a voltage drop.
Battery is a contant voltage source. It is not a constant power source. As you can see, delivered power is dependant on load resistance. The higher load resistance results in the lower delivered power. Can anyone give me an intuitive reason behind this decrease? Figure 1. (a) Original circuit. (b) Equivalent circuit.
The amount of voltage drop depends on the battery’s chemistry and design. Some batteries are designed to handle a lot of current without much voltage drop. These are called high-discharge batteries. They have a lot of internal resistance but can provide more current for a longer period of time.
As more current flows through the battery, it becomes harder and harder for electrons to flow from one electrode to another. This increase in resistance causes a drop in voltage.
When a battery is under load, the voltage reading will be lower than when it is not. This is because the battery is providing power to something else and is not just sitting idle. The amount of voltage drop will depend on how much current the battery is supplying. A 12 volts battery should read around 11 volts when under load.
There is a fundamental relationship between the Voltage, Current and Power in a series circuit using direct current, This relationship was first described by Georg Ohm in 1827. In 1879 James Clerk Maxwell published the mathematical description of the physics involved.
