[Single activity]
Root-mean-square current and voltage
Read and explain the text about measuring what are known as the root-mean-square values of an alternating current. Run the simulation to compare AC and DC supplies. From the graph determine the readings of the voltmeter and based on the readings of the ammeter, ask students to calculate the peak AC current.
