Valid at Peter Pan BMW only and on BMW passenger and SAV vehicles only. Service coupon not valid with any other offer or special. Must present service coupon at time of purchase or service repair order write-up. Some models not included in special offer. Limit one service coupon per person.
RMS Power Ratings: The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. RMS power is derived from Root Mean Square which is a statistical measurement of the magnitude of a varying quantity and is applied to voltage or current.
V(rms)=sqrt(P(avg)/R) The true RMS voltage is measured using the following method. P(avg) is the average power dissipated in a resistor R when a RMS voltage V(rms) is applied. The power is measured by a thermistor and the scale of the meter is calibrated as a ratio of temperature to resistance.This is true for any waveform and frequencies. Note that most meters you use are not true RMS meters.f it is not you will get false results from them if the load on a circuit is reactive such as a motor or if the wave shape is not a pure sine wave. True RMS instruments can correctly resolve various phase relationships and wave shapes to give you a true RMS reading of voltage and current.
