If the effective voltage of an ac receptacle is 120V, what is the peak-to-peak voltage?Select one:a.169.7 Vb.240 Vc.339.4 Vd.84.8 V

The peak voltage of an AC circuit is given by the formula Vpeak = Vrms * sqrt(2), where Vrms is the effective voltage.

Step 1: Substitute the given Vrms value into the formula. In this case, Vrms = 120V.

Vpeak = 120V * sqrt(2)

Step 2: Calculate the value.

Vpeak = 169.7V

The peak-to-peak voltage is then 2 * Vpeak because it measures the total voltage swing of the AC signal.

Step 3: Substitute the calculated Vpeak into the formula.

Vpeak-to-peak = 2 * 169.7V

Step 4: Calculate the value.

Vpeak-to-peak = 339.4V

So, the peak-to-peak voltage of an AC receptacle with an effective voltage of 120V is 339.4V. Therefore, the correct answer is c. 339.4V.
