what would be the appropriate answer choice for this question:
If the batteries in a portable CD player provide a terminal voltage of 12 V, what is the potential difference across the entire CD player?
a. 3.0 V
b. 4.0 V
c. 6.0 V
d. 12 V

thanks alot guys

• Physics -

The "terminal voltage" is what drives the CD player. It is the voltage delivered by the battery compartment. With that information, you should be able to answer the question
