Given that the voltage from a wall outlet is AC if you were to correctly use your digital multimeter to measure the wall outlet voltage to be 120 V, what is the maximum voltage level provided by the wall outlet

Respuesta :

Answer:

   V_{max} = 169.7 V

Explanation:

In an alternating voltage system, the value measured by the measurement equipment is the effective voltage, that is, the average voltage over a period

             [tex]V_{rms}[/tex] = [tex]V_{max}[/tex] / √2

in our voltmeter measure a V_{rms} = 120 V

              V_{max} = √2    V_{rms}

              V_{max} = 120 √ 2

              V_{max} = 169.7 V

this is the peak or maximum voltage of the wave
