Chapter 25: Problem 3

Can the voltage across a battery's terminals differ from the battery's rated voltage? Explain.

Short Answer

Expert verified
Yes, the voltage across a battery's terminals can differ from the battery's rated voltage. The actual terminal voltage can be influenced by factors such as the battery's state of charge, its temperature, and the rate of current draw (the load).

Step by step solution

01

Understanding Rated Voltage

The rated voltage of a battery is the nominal or face value that you would typically find on its label. This serves as an indication of the maximum voltage it can deliver when it's fully charged. Its actual voltage when in use can differ from this nominal value.
02

Factors Affecting Terminal Voltage

Several factors can affect the actual voltage across a battery's terminals. These factors include the battery's state of charge, its temperature, and the rate at which current is being drawn from it (known as the load).
03

Variations in Terminal Voltage

Under low load or no load conditions, the terminal voltage can approach the maximum rated voltage. However, under high load conditions, the terminal voltage may drop. '\[ \]' Temperature changes also affect the voltage; increased temperature generally reduces the battery voltage, while lower temperatures can increase it. '\[ \]' Finally, as the battery depletes, the voltage output will also decrease below the rated voltage.
