d- 13 volts
Explanation:
We can use Ohm's Law to solve this problem, which states that voltage (V) is equal to current (I) multiplied by resistance (R):
V = I x R
Plugging in the values given in the problem:
V = 0.87 A x 15 ohms
V = 13 volts
Therefore, the voltage of the car battery is 13 volts (option d).
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
