A car radio with a resistance of 15 ohms draws a current of 0.87 amperes. What is the voltage of the car battery?
a
17 volts
b
1.3 volts
c
5.8 volts
d
13 volts
d. 13 volts
To find the voltage of the car battery, you can use Ohm's Law: V = I * R
V = 0.87 amperes * 15 ohms
V = 13 volts
Therefore, the voltage of the car battery is 13 volts.
