Root Mean Square (RMS) Voltage and Current

Intro to AC Circuits using Phasors and RMS Voltage and Current | Doc Physics

What is RMS value | Easiest Explanation | TheElectricalGuy


A person touches a wire carrying a 120 V AC voltage. One hand touches the wire, and both of the person’s feet are bare and are touching the ground. Assume skin resistance at the hand and at each foot is <math display=“inline”><mrow><mn>2200</mn><mtext>&#x00A0;</mtext><mo>&#x03A9;</mo></mrow></math>. What is the current through the person’s torso?


<p>An AC source operates with a 0.05 s period. 0.025 s after the current is at a maximum, the current is measured to be 1.4 A. What is the RMS current of this AC circuit?</p>
