The devices are safe to plug in because they are marked with an AC voltage and frequency. Figure 7. RMS voltage is considered only in determining whether a source is suitable for a product.Īlso the devices accept 120v, but the voltage of the AC current is constantly fluctuating. In Figure 7.10, examples of clipped envelopes with CR2 dB (i.e., where the virtual peak voltage Vpeak 5.8 V) and CR4 dB (i.e., where the virtual peak voltage Vpeak 7.2 V) are shown in both cases, they are clipped at 4.75 V. The user never needs to consider anything except RMS current in deciding how many devices can be plugged in. In general, when trying to determine which devices, or how many devices to plug into a circuit without overloading it, should one consider the RMS current/voltage or Peak current/voltage? That includes consideration of possible momentary deviations above those peaks. When the products are designed, the peak voltages and currents are considered. Labels for AC products are marked with RMS values of current and voltage. When manufacturers create power labels for AC electrical devices, what value to they use for the current and voltage? Do they use the RMS of the sine wave? Or do they use the peak of the sine wave? Is peak current/voltage negligible when considering the safety of an AC circuit? Most specifications use RMS for that reason. The idea with RMS is that it gives the measure of the equivalent DC current that will cause the same heating effect. but the voltage of the AC current is constantly fluctuating. Irrelevant as the current determines the heating. I want to plug in two devices which each have a RMS current of 5 amps, but a peak current of 6 amps. In general, when trying to determine which devices, or how many devices to plug into a circuit without overloading it, should one consider the RMS current/voltage or peak current/voltage?įor example, let's say I am using a power strip that can accept a maximum of 10 amps. The peak voltage is the most dangerous part for insulation and personal health. I think "negligible" isn't the right word here. Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts.The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat). Is peak current/voltage negligible when considering the safety of an AC circuit? Or do they use the peak of the sine wave? RMS as that's what will give the measure of heating. When manufacturers create power labels for AC electrical devices, what value to they use for the current and voltage? Do they use the RMS of the sine wave?
