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
5.8 volts
b
13 volts
c
17 volts
d
1.3 volts
The correct answer is b) 13 volts.
To calculate the voltage, you can use Ohm's Law: V = I * R, where V is the voltage, I is the current, and R is the resistance.
V = 0.87 amperes * 15 ohms
V = 13 volts
Therefore, the voltage of the car battery is 13 volts.
