Brown, Red, Brown on a resistor has a value of?
120
Opposition to the flow of AC current caused by inductance is called?
inductive reactance
explain difference of AC vs DC, a diagram is acceptable
diagram or alternating current uses high voltage and a transformer to span long distances, DC uses a battery or another small source, lower voltages for shorter distances
