10.5.1 Rms - Presentation Transcript
- Ir.m.s. = 0.707 Imax Vr.m.s. = 0.707 Vmax
- As total power (PTotal) = V I Then average RMS power = Vr.m.s. x Ir.m.s.
- Power(RMS) = Vr.m.s. x Ir.m.s. Vr.m.s. = 0.707 x Vmax and Ir.m.s. = 0.707 Imax Average power = Vr.m.s. x Ir.m.s. Gives: Power = 0.707 x Vmax x 0.707 x Imax = 0.5 PMAX
- Refer to Electrical Trade Principles p. 215 - 222 by Hampson & Hanssen
