In the US, the conventional voltage seen in a recepticle (wall outlet) is 120 V. How many amperes is required to run a stereo that has a resistance of 494 capital omega ?

Respuesta :

Given that the voltage is V = 120 V

The resistance is

[tex]R\text{ =494 }\Omega[/tex]

We have to find the current.

Current in the circuit can be calculated by the formula,

[tex]I=\frac{V}{R}[/tex]

Substituting the values, the current will be

[tex]\begin{gathered} I=\frac{120}{494} \\ =0.24\text{ A} \end{gathered}[/tex]
