d) 13 volts
Explanation:
We can use Ohm's Law to solve for the voltage:
V = I*R
where V is voltage, I is current, and R is resistance.
Plugging in the given values:
V = 0.87 A * 15 ohms
V = 13 volts
Therefore, the voltage of the car battery is 13 volts.
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
1.3 volts
b
5.8 volts
c
