dark Parallel circuits are preferred in household wiring ensuring that if one appliance malfunctions others continue to operate 4 AC vs DC The Alternating and Direct Currents Direct Current DC flows in one direction like in batteries Alternating Current AC periodically reverses its direction as in household power supplies AC is more efficient for longdistance transmission due to transformers which can step up and down voltage Figure 3 AC and DC waveforms Insert two graphs one showing a DC waveform a straight horizontal line and another showing an AC waveform a sine wave Practical
