Answer:
Current is 4.8 A.
Explanation:
We know that, from Ohm's law that for a current carrying conductor, the potential difference across it is directly proportional to the current flowing through it, keeping the physical properties same. From Ohm's law:
[tex]V=IR[/tex], where,
[tex]V\rightarrow \textrm{Voltage across the conductor}\\I\rightarrow \textrm{Current across the conductor}\\R\rightarrow \textrm{Resistance of the conductor}[/tex]
Now, plug in 120 for [tex]V[/tex], 25 for[tex]R[/tex] and solve for [tex]I[/tex]. This gives,
[tex]120=25I\\I=\frac{120}{25}=4.8\ A[/tex]
Therefore, the current flowing through the hair dryer is 4.8 A.
