Question

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 958 capital omega ?

Answer 1

In order to find the current needed, we can use the formula below:

`I=(V)/(R)`

Where I is the current (in Ampere), V is the voltage (in Volts) and R is the resistance (in ohms)

So, using V = 120 V and R = 958 ohms, we have:

`\begin{gathered} I=(120)/(958)\\ \\ I=0.1253\text{ A} \end{gathered}`

Therefore the current needed is 0.1253 Amperes.
