An AA battery produces a potential difference of 1.5 V. Four AA batteries are placed in series to power a portable FM radio. What is the total voltage of the radio?
6.0 V
0.75 V
1.5 V
3.0 V
Detailed Explanation
Voltages in series are added to determine the total voltage. 1.5 V + 1.5 V + 1.5 V + 1.5 V = 6.0 V.
