How Does Load Affect the Voltage and Current Output from a Battery Pack?
Load affects the voltage and current output from a battery pack significantly. When you connect a load to a battery pack, it draws current from the battery. This current draw causes the battery voltage to decrease due to its internal resistance. Internal resistance is the opposition within the battery to the flow of electric current.
As the load increases, the demand for current rises. This increase in current can further decrease the battery voltage. In a simple circuit, the battery supplies both voltage and current. The relationship between these factors is described by Ohm’s Law, which states that voltage equals current multiplied by resistance (V = I × R).
When the load is small, the battery produces its rated voltage. However, as the load grows larger, the voltage output drops. This drop occurs because the internal resistance consumes some of the voltage supplied by the battery. Thus, increased load reduces the voltage available to the external circuit and affects the total current output as well.
In summary, a higher load results in a lower voltage output and a corresponding increase in current draw from the battery pack. This interplay highlights the balance between voltage, current, and load affecting performance.
