Question

what is the ratio of root mean square value and peak value of alternating current

Answer 1

Hiii there,

● Peak value and RMS value -
- Peak value is the maximum value attained in one cycle.
- RMS value is root mean square value of alternating current in one cycle.

● Answer -
vrms = vm/√2

● Explanation -
- Ratio of RMS value and peak value of alternating current is 0.707.
vrms = 0.707 vm
- Ratio of average value and peak value of alternating current is 0.637.
vavg = 0.637 vm

Hope this helps you...
