Answer:

14.4 V

Explanation:

The problem can be solved by using Ohm's law, which states that:

[tex]V=RI[/tex]

where

V is the voltage in the circuit

R is the resistance of the clock

I is the current in the circuit

In this problem, we have:

[tex]I = 4.5 A[/tex] is the current

[tex]R=3.2 \Omega[/tex] is the resistance

Substituting the numbers into the equation, we find the voltage:

[tex]V=(4.5 A)(3.2 \Omega)=14.4 V[/tex]
