In video #321, we looked at DC current sensors. Today we will look at how to measure AC mains currents, which is much more difficult. And more dangerous because it can kill you if you do not pay attention. And, because measuring AC power is useful in home automation, we will also look at how to measure voltage and calculate power. To measure correctly, we have to learn about phase shifts and power factor. And I will tell you the essential rule to live long around high voltages.
