🔍 Key Concepts

• AC (alternating current) waveforms and how they vary over time • The difference between instantaneous, peak, average, and RMS values of a sine wave • What household and most electrical meters are designed to indicate for practical power use

💭 Think About

• For a pure sine wave, which voltage measure best represents the effective heating or power delivered, similar to DC? • If a meter shows "120 V" in a typical wall outlet, is that the peak voltage, the instantaneous value at some moment, or a standardized effective value? • Which of the listed voltage types would be the most useful and meaningful for electricians and engineers when sizing equipment and conductors?

✅ Before You Answer

• Make sure you recall that instantaneous voltage is just a snapshot at one moment in time, not a long-term measure • Remember that peak voltage is the maximum value reached by the waveform, not necessarily what we commonly quote as "voltage" in power systems • Think about which value (average, RMS, or peak) is normally used when we say a circuit is "120 V AC" or "240 V AC"—that’s the type most digital multimeters are calibrated to display
