Current fraction of a sinewave

  1. Jun 18, 2015 #1
    So PWM can simulate a decrease in voltage when useing a stable amplitude.

    10v50% duty cycle is 1/2 the amplitude meaning 5v. And if this is through a standard resistor then you will see 1/2 the current.

    But what about a sine wave? What fraction or percentage does this come out to be? What current will you read with a 10v sine wave through a 5ohm resistor?
