Answer 2

Answer: C. 14 volts

Step-by-step explanation:

According to Ohm's law, the voltage
`V` is:

`V=R.I` (1)

Where:

`R=3.2\Omega` is the resistance of the clock

`I=4.5A` is the electric current that flows throgh the clock

Substituting these values in (1):

`V=(3.2\Omega)(4.5A)` (2)

`V=14.4V\approx14V`
