Answer: C. 14 volts
Explanation:
According to Ohm's law, the voltage [tex]V[/tex] is:
[tex]V=R.I[/tex] (1)
Where:
[tex]R=3.2\Omega[/tex] is the resistance of the clock
[tex]I=4.5A[/tex] is the electric current that flows throgh the clock
Substituting these values in (1):
[tex]V=(3.2\Omega)(4.5A)[/tex] (2)
[tex]V=14.4V\approx14V[/tex]
